Gibson GA-15RV tube amp

[Szyderca]

Hi,

anyone built it ? I want to diy this amp but I dont find the schematic ! I found the old one but thats with two 6L6 in the output and a 6SL7 in the driverstage but the newes version is with 2*12ax7 and 2*el84 so maybe someone has the schematic and can send it to me

How does this amp sound like ?

I had a Gibson MinuteMan GA-20RVT - loved it. The 15 isn't so different.

See

is a link to over 30 people raving about their GA15RV amps.

Some of them have contact info at the end of their posts. If you don't find good info here, consider sending a few emails.

One guy says...
"I actually had very good response [from Gibson customer support] when I've called Gibson back East. I got a schematic when I had my other Goltones."

I too have received decent responses from many manufacturers when looking for old parts, documents, etc. Though often, they're out of stock.
