Amplifier Discussion / Re: Peavey Bandit as speaker cab
« Last post by joecool85 on November 18, 2021, 11:25:59 AM »
I've seen it done before where the speaker goes to a female 1/4" jack, the amp has a female 1/4" output jack, and then when using it as a combo you use a short 6" speaker cable to tie them together.  Want to power a different speaker?  Just unplug the speaker and plug a longer cable from the amp output into another cab.  Want to use the Bandit speaker (like you do) as a cab for another amp?  Just unplug both ends of the 6" speaker cable and plug a longer cable into the Bandit from the amp serving as a head.  Clean and simple.

I agree that you need to run the speaker wires into a Jack Socket mounted in the cab of the Bandit.
I'm not sure what you have now, but you could get a small box, like a pedal box 1590B, and mount it in the cab, and then mount your jack socket in there.
You will need a small patch lead with 2 x 1/4" male plugs on it to connect the Peavey speaker to the Peavey Amp.
I don't know where you live so I can't recommend a shop.
I Like Tayda for most of my parts online, but there are so many other great shops to get gear from.
Tayda is very cheap, and the postage is very good too in my opinion, but I just fiddle with stuff for me and family, home use.

Hi Enzo thanks for the input but my concern with that setup is when the external Amp plug is inserted into the socket in the bandit cab, the Hot tip of external Amp output will momentarily be in contact with the neg terminal of the bandit output (until it is fully inserted)
With both Amps powered off that would work but there is always the chance one forgets to turn off amps.
As you noted the speaker neg of the Peavey output is not at ground. :-\

If I get time tomorrow I'll try to pull the back off one of my Amps to show how my setup works.
I agree the idea of a hot tip floating around is not ideal.

I believe most bandits have the speaker wires hard wired and drop through the bottom of chassis which makes it harder to find a good safe work around.
My amp has a chassis mounted speaker socket which allows one to disconnect the cable from the amp therefore no floating plug.

The  speaker in my combo Amp is wired to one 6.5mm socket mounted on a short alloy angle. so I just remove the speaker cable from the internal Amp and then plug in the external amp with a longer speaker cable.
So it's darn near impossible for both Amp outputs to ever come in contact with each other.

A Double Pole switch would work but would have to be quality Break before Make.
The quality of some switches I've used is not great as I've had a couple fall apart inside.
Phil.

Just my opinions here...

I don't like the output of the bandit on a male plug.  If it is not plugged into a jack, then it is just flopping around, and that tip could touch something grounded while the amp was unintentionally powered up.

The simplest thing is to put a cutout jack on the rear as others have suggested.  Use the Bandit as its own enclosure.

ALWAYS turn power off when connecting or disconnecting speakers.

Mounting bracket?  A piece of aluminum bent 90 degrees.  One flat surface gets a couple screw holes and is screwed to the wall of the cabinet.  The other flat surface gets a hole to fit the jack.

I recommend CLiff jacks.  They are all plastic so there is never an issue with the jack grounding itself.  Be aware that the cold side terminal of the speaker is NOT at ground in many SS amps, Bandits included.

Jack wiring?  On the Cliff jack, wires from amp chassis to the tip and sleeve cutout contacts, and the wires to the speaker from the tip and sleeve contacts.  That leaves normal operation.  PLug a remote amp into the jack and the amp chassis is disconnected and the outside amp connects to the speaker.

Hi phatt,

thanks for your input.  I think that what you mean by "6.5 sockets" (6.5mm?) are 1/4" mono jacks.  I'm pretty sure that it's safe for an SS amp to not be connected to the right speaker load; if the jacks aren't connected then the power amp sees infinite impedance.  I'm curious as to what kind of "enclosure" I would use. You mention using a bracket, is there something pre-made that you would recommend?  While it may be a little hokey, I'm picturing a small plastic box with a hole for the input wires currently going to the speaker lugs that would be connected internally to the jacks and then a hole going back from the "return" jack to the speaker lugs. I assume these would just be isolated (as in no electrical connection betwixt the two) mono jacks.  I could then attach either two sided tape or similar to the enclosure and stick it on the bottom of the amp's chassis.  I'm suggesting using an enclosure to protect the jacks from accidental shorts.

I found a thread in the tdpri forum that suggested a few other different options.  The first is very simple.  Just wire the two wires currently going to the speaker to a male mono plug, and add the female counterpart that connects to the two speaker lugs.  This way, I could just disconnect the plug from the Peavey power amp from the female jack leading directly to the speaker and insert the speaker cable leading from another amp.  There's an alternative suggestion to use a cliff jack which in theory would disconnect the Peavey power amp once the external speaker cable is inserted.

Here's a link to the discussion that perhaps more clearly describes what I tried to capture in the previous paragraph:
https://www.tdpri.com/threads/converting-a-combo-amp-into-a-cabinet.352192/#post-5487168

In particular, look at posts 5 and 6 on that thread.  For the cliff jack option, it would probably be best to have both amps powered off when making that connection.

I welcome your feedback.  Thanks so much.  Also, feel free to point me to a good resource where I might purchase suitable mono jacks and some sort of enclosure.  I imagine you were thinking of using some sort of metal scrap material and bending it into the shape of a bracket.

The attached image shows a cable that is almost what I need for the simple option I mentioned above, instead of a 1/4" plug I'm looking for a 1/4" jack or possibly could use a female/female adapter.

Just a word of warning,
When switching 2 Amp outputs to the same speaker there is always a risk of damage to one or both Amps if the 2 amplifier outputs ever join, even momentary. You would have to make sure the switch is a break before make design for that to work.

My option would be to cut the speaker wires in the Bandit and insert 6.5 sockets.
So the Bandit output goes to one socket while the Bandit speaker goes to the other socket.
Both sockets can be mounted on a bracket and screwed to the insidewall of Bandit Cab. Mark one socket as Bandit output and the other as speaker input.

Now make up a short speaker lead to join the sockets and jumper the sockets to use the Bandit's internal speaker,, then just remove the jumper and plug the other amp output into the speaker input of the bandit.
This way the 2 Amps can never accidentally come in contact with each other.
I've done this idea to a few rigs and works fine.
I'm sure others here my have other options
Phil.

Amplifier Discussion / Peavey Bandit as speaker cab
« Last post by weinstev on November 17, 2021, 02:24:52 AM »
I recently bought a used Peavey Bandit in hopes that I can convert it into a multipurpose tool.  My other two amps are 8" combos, a Vox Pathfinder and a Randall RD1C.  Both have line and speaker outs, and the Randall has an effects loop as well.

I'm looking to do a couple of different things with the Bandit, but I'll focus on the first of those for now.

I'd like to use the Bandit as an speaker cabinet.  With the Bandit turned off, I'd like to simply connect the speaker outs of either of the other two amps to the 12" speaker in the Bandit.  What I'm envisioning is connecting the two wires coming out of the power amp and currently going to the speaker of the Bandit to some sort of switching jack into which I could connect the speaker out from either of the other two amps and then route back to the Bandit speaker.  The attached image shows the two wires to which I am referring.  I'd like to mount/attach this switching jack to the underside of the Bandit amplifier's chassis, preferably without having to drill into it.

So, how best to accomplish the goal of being able to connect a speaker cable from another amp to the speaker of the Bandit?

Being able to use the speaker in a combo as a speaker cabinet seems like a fairly common thing to want to do, but I'm just not sure what is the best way to go about doing this.

Thanks for your help,
Victor

Guitar News / Get your digital groove on - Peavey announces new Vypyr line updates!
« Last post by joecool85 on November 13, 2021, 09:07:42 PM »
Peavey has announced updates to it's Vypyr series of amplifiers.  Now they have more amp models, more effects, and a reworked semi-open cab to "improve volume and tone".  I'm not normally big on the "a billion options in one amp" units, but I have to say, I'd like to sit down and play with one of these.

Pricing is $179, $349, and $499 for the 20w X1, 40w X2, and 100w X3 respectively.

Schematics and Layouts / Re: My SMD solder practice PCB - Micks Thick As A Brick
« Last post by Tassieviking on November 09, 2021, 09:48:00 AM »
I find Kicad great, I have only used it for less then a year now I think, but I am making up my own foot-prints and I have made some PCB's as well. :dbtu:
I am not sure when I will attempt the SMD practice as I am going to build some SS amps first, The Sunn Beta amps both Bass and Lead and also some Marshall Mosfets, and I also got some PCB's coming for the Sunn SL160/SL260 amp, but the SL160/SL260 is not supposed to be that good sounding.
The practice board should make up a BTDR2 on one half and the other half is the 5V reg, and the in/out amps with speed etc.
You can make a stock BTDR2 or an adjustable decay and frequency one if you want with that PCB.
Cut the board in half and join back to back and it should fit in a 1590A pedal.
I want to experiment to see if I can use this in a SMD sunn beta amp pedal with reverb and class D power amp eventually. (1590BB)
That's if it works, if not at least I will get some soldering practice and have fun doing it.
