Picked up a little history this week end

A Johnson Viking Thunderbolt
Man this thing is heavy!
But she is a beauty. Only a few nicks and a scratch here and there.

The owner changed out the 4-400's with 3-500z's. He thought it was a plain tube swap. When he put the originals back in he then found that when you hit the plate switch it appears to be in tx mode. Other words the OD3 and OC3's start the glow, there is a hum and the tubes will start to turn orange. So looks like he took something out in the bias circuit since the tubes are turning orange.

I can not believe the appearance of this amplifier. The inside is so clean. I will post some pics of the inside later. I was already offered 2 grand for it.

Anyway this is a beautiful piece of history.
