This is becoming quite common on small amps and heads.  The Yamaha THR series does this, as does Orange Micro Terrors, Hughes & Kettner "Spirit" amps, Vox MV50 series and more.

Have you tried making your own PCB?
I like using KiCad to make up PCB's for whatever I want to build, I get 5 PCB's from JLCPCB for the price I can order one from someone else.
If you download KiCad you should be able to check out the PCB I made for the Sunn Beta, my design is adaptable for the Bass or Lead version, just install the right components.
I guessed at the spacing of the pots so they will not match the original amp, but close enough for me.
Look up: https://www.ssguitar.com/index.php?topic=5080.msg39729#msg39729

I think I left all the files there, including the Gerber files I sent to JLCPCB when I ordered my PCB's
If you want to use my PCB just order some.
I think I have tested the Bass version of my PCB, but not completely sure, I have had a messed up year so far.

Quote from: willpirkle on June 13, 2022, 10:08:21 PMYep - I didn't get the name of the company who did all of them, but was told something similar about the power amps, and that each model was designed in partnership with each respective company, so there are differences in the preamps that could be interesting to study. Have not seen any schematics for any of them tho.



It is the parent company, Boutique Amps Distribution.  http://boutiqueampsdistribution.com/

They own a ton of companies now:
Bogner
Diezel
Egnater
Friedman
Morgan
Soldano
Synergy
Tone King
Wampler

The Newcomer's Forum / Sunn Beta Lead/Bass Builds?
Last post by comradehoser - June 14, 2022, 09:22:44 AM
Hello folks, first-time post.

Originally, I had joined because I was trying to suss out the issues of my daughter's Orange 12L amp, and it turned out to be the 4558 chip.

But!  I have built several pedals and find electronics pretty fun.  My favorite pedal currently is one that I built myself--the Sunn Beta Lead/Bass based on the PCB by PCB Guitar Mania and kitted by Das Musikding.  It had nothing but issues, but when I finally got it fired up--just wow.  Really amazing cleans, massive distortion, and the EQ is the stuff.  No idea how close it is to the real deal, but it made me want to try to build the actual thing.

I can find schematics, but other than wiring to board, and creating my own enclosure, are there any other options?  And yes, I did see the option to buy a broken one and fix it, but even that is suffering the "Peavey syndrome" and what was once affordable is now desirable and boutique and costs the money$$.  Is it kitted somewhere?

Hehe

Yeah that's from the same company that released the mini Friedman BE, the mini Bogner and the mini Diezel VH. Soldano just probably tweaked the voicing.

I am also curious about its preamp. The power amp is 100% some chip.

Amplifier Discussion / Re: Do Electrolytic Caps Age ?
Last post by dimkasta - June 13, 2022, 07:10:58 PM
Yes electrolytic caps definitely age. But it's hard to say how much life exactly you can expect from them. It depends both on the usage, but also on the storage conditions and their quality. 20+ years is the point where I would start worrying. A quick way to get rid of duds is to see if their case is bulging or leaking.

A quick sample from the internet



I would still worry though. Even if they have no visual problems, they can still be duds. A safer way is to test them with a multimeter or even better an LCR or ESR meter.

You mention wimas. These are probably film and these age in a much much much slower rate. The most usual problem with them is oxidization of the wires (which can be solved with some sandpaper)

Amplifier Discussion / Do Electrolytic Caps Age ?
Last post by Tassieviking - June 12, 2022, 03:57:08 AM
G'day all
So my father died a week ago,and my brother 3 years ago and mum 5 years ago.
Going through all the stuff in my fathers house I have found lots of Electrolytic caps,
Some are around 6800uF 65V, 2200uF 80V, etc. I know these used to be my brothers but he moved overseas about 20 years ago.
Will they still be ok to use in new amp builds or should I scrap them, they have never been used.
There are also bags full of 1uF, 10uf, 22uF etc, never used and heaps of WIMA box caps.
I have to ship them over 2000km back to my place so I only want to keep good *s!!t*.
???

Thanks Enzo,

I took your advice and removed the reverb tank. No springs broken or out of place. I did take some Deoxit to the RCA plugs on both sides and gave the reverb pot a good dose too, working the knob back and forth for a good long time. Reassembled and voila! A working reverb and no startling pops when I adjust the level. Amazing!

So glad I discovered this forum! Please consider this post answered.
