Putting the external 8 ohm 4 x 10" cab in series with the internal Weber speaker would put a 16 ohm load on the amp.  How will the power be applied over the 5 speakers total?

......

I suggest you add a plastic (insulated from chassis) switching external speaker jack, so when nothing is plugged in, you use the internal Weber; then when you plug the 4x10" the internal gets disconnected and the external gets full power. ....

Thanks!.  This model Envoy (silver stripe) already has such an external speaker jack.  I guess that's what I'll have to do.

g1,

Peavey sold the amp with their own in-house made 6 ohm speaker.  The reason was so that they could advertise it as a 40 watt amp.  With an 8 ohm speaker it puts out about 35 watts.

I swapped out the Peavey speaker for the Weber 8 ohm. 

Putting the external 8 ohm 4 x 10" cab in series with the internal Weber speaker would put a 16 ohm load on the amp.  How will the power be applied over the 5 speakers total?

Thanks!

I am looking at putting in an effects loop into my Envoy 110 TT silver stripe.

I've been looking for an effects loop kit for a ss amp and all that I find are kits for tube amps. Here's are some examples:

Does anyone know of a general purpose effects loop kit that will work with a ss amp? My budget is $100 or so.


Thanks!

Thanks!

The schematic for the Peavey Envoy 110 TransTube silver stripe 1995 is attached.

It is also here:

I have a Peavey Envoy 110 TransTube silver stripe (circa 1995) amp.  The lowest speaker impedance load it can handle is 6 ohms.  Is it possible to mod the output stage so that it can safely handle a 4 ohm load?  This would allow me to use an external speaker with the internal speaker (a Weber 8 ohm replacement).

Thanks!

I built a MIDI guitar from a gold Squier:



Full story on this build here:

http://www.squier-talk.com/forum/squier-stratocasters/14351-goldie-part-2-midi-lots-photos.html


Now I'm setting up the amp.  I choose the Peavey Bandit 112 SIlver Stripe and had a new cab made for it to hold the amp and two rack MIDI devices:







The MIDI controler is a Yamaha G50 that will drive the Alesis QSR MIDI sound module.  Output from the QSR will go to the Effects return.  The Bandit 112 will be modded to provide switched 110 AC power to the MIDI rack devices and I will put a set of effect loop jacks on the rear of the chasis for easier cabling.

Next to do is the custom cab with speakers (I'm thinking a 15", with a 12" and 10") and a new pedal board that will control it all.

Parts are in from Peavey.  First mods in progress.  Need some dry weather!

I have a Rage (same amp without the reverb) and love it. I did a lot of tweaking. I listened to what I liked about the clean and distortion and what I didn't and changed a couple values, added a couple caps, and was pleased with the results. I let a little more low end and added a bright cap to the master for the distortion to sparkle the distortion up at high gain levels. I added a switch to the distortion channel to change from a vintage toned overdrive to a scooped mids modern sound, copying the circuit from the next generation of Rage amps.

I added a parallel effects loop, and changed the wimpy 8" speaker to a 10", which improved it a lot. I used an 8 ohm speaker and added an ext speaker jack to run another 8 ohm extension speaker.

I found an old ART, compact multi-effects unit, and put it in back of the amp, patched into the effects loop. I put an AC socket under the chassis for the AC adapter for the ART. There is a reverb program that works perfectly.

I wired the amp to use a footswitch for channel switching, putting a relay in place of the channel switch, and put an LED in the switch hole. The footswitch also has an LED.

I think I replaced the TDA2040 with a TDA2050, improved the heat sink and put in larger filter caps, not to increase power but to increase reliability and headroom.

It's a little beast. I love it. The best mod is I replaced the grill cloth.

Now that's what I'm taking about!!!  The pawn shop thatsold me the Blazer also had two Peavey Rage amps priced at $65 & $50 - way above the Blazer.  Go figure.

Care to share the details of your mods?  I have the schematic.

Parts arrived today from Peavey so tomorrow I start my mods.

Phfff ... lotas small bits.  No ploblemo.   8|  Pity the poor keyboardist lugging a Hammond B-3 containing a giant gearbox, and a Leslie the size (and weight) of a family fridge.  Then you don't need roadies, you need a couple of tame gorillas.   :duh

+1000   :lmao:

I forgot that most jacks are PCB mounted.   

Forget it.  I'll just use the adapters.  Thanks!

.....  And if you have ever tried moving a Marshall stack ...  xP

Worse:

Here's my rig:



Do I ever need a roadie!

Thanks all.  After some thought I decided to keep the amp.    

Of course I'm going to mod it.  First up is a channel & reverb foot switch.  Shouldn't be too hard to do.

Next will be a pre-amp out for recording.  Maybe an XLR balanced out.  Ideas?

Next would be an effects loop.  I think I will look at the effects loop circuit from the Bandit 112 to see if I can copy it.

Why all the work on a 15 watter?  'Cause if I screw it up no great loss!

Other ideas?

Does anyone know of a supplier for 3.5mm stero jacks that will fit in a 3/8" hole?

I want to convert the 1/4" jacks on my amp's aux in & headphone connectectors to 3.5mm size.

I don't want to use an adapter that allows a 3.5mm plug to plug into a 1/4" jack.  I have those.  I'd rather just replace the jacks.

Thanks!

Well, as I'm leaving the Orlando area on Thursday, I made a final pass through the pawnshops today to see what treasures I could find.  I hit the last 8 today having been in 12 others on Saturday.

Walking into a Cash America shop, I see a battered Peavey Blazer 158 Silver stripe and after some negotiations I walk out with it for $18.78 plus tax - $20 total





Obviously it's a very rare model as it has a YELLOW Peavey logo:



I'm thinking that it must have beed a custom amp for the Sultan of Brunei with that yellow logo.  The logo alone is worth $26.73 as they are very very rare !

It must have been a factory relic as it's missing the all the top corner pieces:



When I looked at the back I knew it was a very hot amp as the rear back has been totally removed to allow greater air cooling to get to the amp.



Alas, when I got it home the disappointments sank in.  It has the following deficiencies:

1.  None of the pots have any scratching sound.  For a relic I expected at leat one pot would be scratchy.  What a disappointment!

2.  Both channels work.  I would expect at least one channel to be out if not both.

3.  The reverb is too strong.  With a relic the reverb should be weak.

4.  The overdrive channel is usable.  The OD channels are supposed to be tinny and scratchy.

5.  It's too loud for my apartment.  These relics are supposed to be for display, not to actully work and make noise.


With these faults I'm thinking about taking it back tomorrow and getting my money back.  What do you think?
