Believe whatever you want.

And although I sometimes think things about for sale threads, I hold back from thread crapping on someone's sale.

IMHO, shipping is killing this, which is why I really wanted to make a local sale on these, but no local interest.

It's just I've been too busy with other stuff and lazy to test/troubleshoot these amps.

I also think same thing. Post pics of wiring and parts please.
Possible fried before it work and no just dump?
Cheap china transformers not sure if work,
if not working etc = sheet metal price.
Maybe Hammond transformer you sold was for this project?
Hope if honorable person list here,

NEVER able to get them working... you kept the tubes for a new project?
Just curious, because it looks like a simple design and easy to repair any problems, there is not even a pcb!.

Did the amps play some music? what caused it not to sound anymore in both. This is the information someone wanting to fix it would like to know.

Hey all, enough negativity. There are no claims being made. If I lived locally, I would take them as is for $300. Odds of all the transformers being out is small, the risk is small and there are some good articles about these amps being quite good with some small circuit mods.
This is a nice deal for someone local. If shipping to Denver was cheap, I might still buy them.

Hi folks,

I have several Ming Da amps. Ming Da transformers are excellent. I don't know if any of the transformers are bad but I think that this is a good opportunity to build a 300B amp with your own circuit.

I pm'd Randy about buying them and will do so after next months paycheck if they are still available.

Don't mean to troll, but why didn't you just check the tranny primary and secondary for at least continuity and remove some doubt? Too much work, or just feel the need to be uncertain to make the sale?

Plausible Deniability: The act of someone who actively avoids gaining certain knowledge of facts because it benefits that person not to know.

Its 2 minutes of confirmation. It would have served you just as well as everyone else that may have been interested...correct?
