Next question.

You don't have the MUTE activated somehow, do you?

Hate to be the one to say this, but, most of those amps have a fuse. Is it good?

Addendum
I see the main fuse up by the transformer. I'm sure you checked it, but gotta rule it out.

The bonus about today's electronics is that most of the problems are broken solder joints or the old standby, electrolytics. Wife's phone started having problems charging and since the microUSB plug started to wiggle, but only in her phone, I ordered a new charging daughter board. It was harder to g...

Is the NAS mounted with a drive letter, such as K: or L:, or is it via a different pathway? Could be the older DBase software cannot read past a certain letter or "needs" a path set in some setting.

Yeah, I've seen some weird crap over the years.

Last I saw parts like that was in MCM. Not sure if Newark has them.

The NAS doesn't have either file encryption or file compression enabled, does it? Could affect how the files are dealt with.

I restored an old RCA Cathedral style radio years ago. I replaced all the capacitors with new ones. When I fired it up, It played well but all I could get was modern music :???: . (Don't be critical! At least it's another post...) Reverse the leads on the antenna. That way it'll reverse the radio w...

AFAIK, that shelf life refers to sitting unused before any drying or deterioration of electrolyte may occur. This doesn't mean they won't be any good, it just means they MAY start exhibiting signs of degradation in one or more of a varied set of parameters: actual capacitance, voltage rating, heat r...

While you are at it, give this a watch. Quite handy to know.

Well, son didn't bring guitar as requested, so I'll have to go to storage and hopefully find the one he told us to hold onto until he buys a house. And even then, I don't know if I have a 1/4 plug. I'll figure something out. No worries. "If it hadn't been for those meddling kids!" :D CeaSaR

Well, the board with the actual power amp is set to use heaphone levels, presumably from a digital player such as an MP3 player or a cell phone's heaphone output, which, in this case are rather low on all accounts. Besides, just based on the resistance shown, it should only draw a few milliamps. And...

But that doesn't fit the constraints I have. So... Here's another one I found and a Sim thereof. Granted, Rs is arbitrary, but without knowing, this is a middle ground according to the text. Also not worried about super fidelity, since it's for guitar and I want distortion at harder hits and hotter ...

So, no clue as to why it didn't work so well last time, but here's another screenshot that should look much better.
