Guitar News / Biggest selling amp this year - Mustang Micro!
« on: November 23, 2021, 08:56:58 PM »
According to musicradar.com and reverb.com, the biggest selling amp of the year (in volume, not dollars profit) is the Mustang Micro.  Interestingly, DSP and solid state in general completely dominated the top 10.  Tube amplifiers only showed up in 4th, 5th, and 8th in the top 10 with 4th and 5th place being Orange's micro series amps that use tube preamp and solid state power amps.  Rock on SS gear!

Guitar News / EHX Howitzer - not sure how I missed this one!
« on: November 22, 2021, 11:42:40 AM »
Back in March, EHX released the 15w Howitzer pedal amp.  The difference with this and the older 5mm, 22 Cal, and 44 Magnum, is this has a full preamp in front!  3 Band EQ, normal and bright modes, gain, and master volume.  It also has an effects loop if you want to add some reverb or other inline effects.  Nice little class-d amp with reasonable preamp in front.
 I think that from the clips I've heard it sounds great clean and with light overdrive.  When you crank it into saturation it leaves a little to be desired.  With a street price currently at about $140 USD, it's still hard to beat though!

Positive Grid is releasing a wireless foot controller for their Spark amp.  Dubbed the Spark Control, the controller connects via bluetooth and allows the guitarist to "change presets, toggle effects, control backing tracks and a ton more".  Honestly, wireless control of an amp is something I never thought of, but now I don't know if I can live without!  What a great idea!

Price TBD

Amplifier Discussion / Re: Peavey Bandit as speaker cab
« 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.

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.

Late this summer, Victory released it's new amp head called "The Kraken".  It uses a couple military spec tubes for preamp duties feeding into a 180w class D solid state power amp section.  Boasting two channels, reverb, 3 band EQ, footswitchable channels, effects loop, and simulated speaker outputs - this little guy has it all...if you can cough up a cool $999 USD.

Amplifier Discussion / Re: 80's Era Roland JC50 blows internal fuses
« on: November 07, 2021, 08:47:29 PM »
I really appreciate all the suggestions from everyone. I popped over to a local vintage guitar shop in town on the off chance that they would have a similar headphone jack as a spare part. They had something very similar to I bought it for $7. As it turns out, the switching inside the jack is identical to the original. Even though I rang out all the connections on the old one, and everything seemed to be working, I went ahead and wired up the new jack and installed it. It ended up working perfectly. I'm guessing that perhaps the contacts internally were corroded, which may have loaded the circuit more than expected but that is a wild guess. Either way, I'm happy to say that the new jack worked.  :)

Good job getting it fixed up!

I love using KiCad, works great doesn't it?  Let us know how the SMD practice goes, I've yet to try it myself.   :dbtu:

Also, I've been thinking about trying some PT2399 reverb or delay circuits.  I'll be interested to see how this comes out.

Guitar News / Bogner Ecstasy Mini - The mini solid state amp that rips
« on: November 04, 2021, 02:04:29 PM »
Bogner has done it again, this time on a mini level.  The Ecstasy Mini is an absolute face melter.  Street price is $329 USD.

Honey Amp / LM386 specs - max wattages etc
« on: November 02, 2021, 10:49:11 AM »
All data below based on LM386N-4, 8 pin DIP with 1.25w package dissipation, and max PSU of 22v

Current datasheet from TI: https://www.ti.com/lit/ds/symlink/lm386.pdf?ts=1612350151545

Maximum power without heatsink, sorted by speaker output in ohms:

4 ohms (Figure 7 on datasheet) = Max 0.35w @ 6v (clean 0.25w) [Min 0.35w @ 6v]
* Need heatsink above 11v
* PSU recommendation: 7.2v NIMH or 7.4v Li-ion

8 ohms (Figure 8 on datasheet) = Max 0.85w @ 12v (clean 0.5w) [Min 0.3w @ 6v]
* Need heatsink above 14v
* PSU recommendation: 9.6v NIMH or 11.1v Li-ion

16 ohms (Figure 9 on datasheet) = Max 1.6w @ 16v (clean 1.2w) [Min 0.2w @ 6v]
* No heatsink required
* PSU recommendation: 11.1v Li-ion, 12v SLA or 14.4v auto power

Plugging in mono 1/4" plug into stereo headphone jack expecting stereo plug?  That could cause shorts.

The Newcomer's Forum / Re: Busking Amp for Bass & Vocals
« on: October 19, 2021, 12:01:23 PM »
I just looked at the TDA2003 spec sheet, it looks like you would get 4 watts at 12 volts, not enough for bass in my opinion, but I am not an expert.
If you have the kit, build it and run your send/line out/ to effects output of your amp into it, and run the output to a separate cab and see what it sounds like.
Or get the signal from your stereo/phone/MP3 player and try it, see how loud the music sounds.
If its not enough the just get another amp module, like I mentioned before, the TPA3116D2 has 15 watts at 12v on the spec sheet at 4 ohm speaker.
You will not us a lot of extra power with a TPA3116D2 if you keep the volume down.
Class D power amps are very efficient and only use a bit more then what you use, if you use a 100w class D amp and only turn it up to 10Watt you will only use about 12-13 watts of power, at least that's my understanding.
Check the spec sheets of the power amp you are thinking off using and find the power rating for the voltage you intend to use, that's what I would do.
Class D amps don't need big heatsinks as well which saves money and weight.

This is correct.  One thing to note though is the TPA3116D2 is an SMD component and difficult to solder.  TPA3122D2N is a through-hole component and much easier to work with.  There are several kits available with this chip, or you could do something on your own.

Looks like a class D amp would be up your ally.  I've been eye-balling this circuit for a while:https://www.parts-express.com/Sure-AA-AK32151-2x15W-Class-D-Stereo-Power-Amp-Kit-TPA3122-320-322

Amplifier Discussion / Re: First attempt to do upgrade

      I posted this in wrong forum sorry for that
       Could someone move this to beginner forum

          Thanks

No need to move this post, we're pretty loose on what goes in which section - chill place around here.

For us to help you in any meaningful way, we're going to need some pictures of the inside of this little guy.  I've never seen anything quite like it, so not sure where to even start.  My guess is you would need to build a basic preamp to sit in front of this amp, then you would start to get more of a "guitar amp" sound from it.
