What is it with these amps???
« on: July 12, 2011, 06:34:08 pm »
Hey there fellows,

Here's a question, there are these Conn organ amplifiers that ran two pairs of 7027A ouput tubes and 1 pair of 7868 output tubes.
The question is, what is it that makes them worth their weight in gold? I had one one time and I reused the 7027 output transformers for use with 6L6's and I thought they were pretty good OT's, but everything else seemed to be kind of plain. The PT uses a voltage tripler so I tossed that rather than fool with it.
Anyway, I have been trying to watch for another one for the OT's, but they are selling for rediculous prices. Below is the item number for one that sold today for 152 bucks plus shipping and didn't even include tubes.

The one I had before, I paid like 25 bucks for it and used the OTs and threw everything else away. I wish I had kept it whole now so I could sell it for a small fortune. (mine had all the tubes).

I imagine people are going after the transformers?

Like I said, the OTs were good, but good lord, they weren't that good

Sorry, I meant the big PTs. Maybe someone somewhere has found a use for something that big?

Probably 100 dollars worth of copper in those things.

Audiophiles.

They will pay silly loads of cash for those tubes and trannies.

I have several Goodwill/Salvation Army type stores around here and check every Monday and Friday and get perhaps 10 good organs a year.

The Hammonds get fixed up and sold to keyboardists, the rest is fodder for the next amp build, except those Conns.

They get the EBay treatment
