Woo amps are much easier to visualize and work on and they do not have a DC servo circuit added to it. Sorry for your loss.
There is nobody else to blame but yourself due to the mods you performed yourself. Electronics don't die randomly, there is a sole reason for it.
Sorry for your loss.
But if you post pictures of the PCB myself and the rest of the community here can help identify, mitigate and fix the problem your amp has experienced.
Or go the expensive route and get it checked by a qualified tech.
Email sent to David at Little Dot......NO REPLY.
I contacted a local repair shop that works on tube amplifiers, they NEED a circuit diagram to work on the amp.
Looks like it is time to buy a WOO AUDIO WA22, at least their warranty is actually worth something.
Instead of Woo, I would pursue your previous comment about making an amp yourself. There are lots of DIY designs out there and you seem to be interested in modding and such. I say go that route.
Thanks, can you or anyone else point me to some designs? I do not know where to look, who to trust, or which designs are good or bad. I would really like to build my own amp, but where do I start, where do I get a design/circuit diagram from?
OK, thanks for the advice. I have looked at the fuses, they look OK but I need to test them (I have seen fuses that look good but test as dead).
There was a very strong electrical burning smell! Sudden and very strong. So I expect to see a burnt component. My nose tells me that one of the resistors I replaced (at the edge of the board) or a small capacitor beside it is the source of the burning smell. I need a multi-meter.
Woo stuff is all aesthetics, nothing special about the sound for the price.
supposedly using a tube rectifier lowers the switching noise from the SS PSU.
Not sure if i buy that since the difference probably isn't noticeable by human ears.
But it sure does look pretty.
