Default F2 Zen Type

Hello everyone,

What can you guys (gals) tell me about this F2 Zen type amp? I purchased this from an individual who makes many types of Fx amps and chip amps. I'm just looking for comments about the tranny quality, caps, and any other info concerning quality or upgrading potential.

Thanks

Spiro

Why so impatient?

Well, anyway, here are my rather harsh comments:

Starting with the transformer...it doesn't look too big. 130VA seems pretty low. Toroidals are usually preferred due to their lower stray field.
The PSU's caps are standard Nichicon. Can't say anything about the resistors, at least the power rating should be okay.

The wiring is really bad, inputs in parallel, small diameter all over, nothing properly twisted or shielded and crossing at arbitrary angles. And whats with the cut wire (green-yellow) coming from the PSU board?

Is there even an earth connection? It looks like the chassis is floating. If this is the case it's very dangerous as this constitutes a shock hazard. I also don't see a fuse. This and the bare contacts on the transformer's primary make this amp a deathtrap. You seriously have to fix this if you want to use this amp. I wouldn't plug it in before these problems are solved.

The soldering looks looks sloppy, no trimming of excessive leads, no love.

Who builds something like this?

Not too good. Highs are distorted, bass is loose...mids suprisingly are ok.

Not a NP worthy device...this is what I feel like after listening to it


WHAT TOOK YOU GUYS SO LONG...jeez...

Anything I can do to improve it?
