Re: A 1970 hybrid amp
A hybrid amp has a pre amp and a tube amp? I guess I don’t know anything about hybrids. I’ve even avoided buying a Prius because I don’t want to drive anything that runs on both steam and diesel.

Re: A 1970 hybrid amp
It can actually be two different styles. Some have a tube preamp and solid state power section. Others have a solid state preamp and a tube power section.
I'll have to look this one up.
Edit:
Is this amp the KV40, 2x12 vertical combo by chance?

Re: A 1970 hybrid amp
It's hard to find info, I'm pulling my hair out.
As far as I can tell, I haven't opened it yet. From web research I think it's either a Hofner made by Schaller or a Schaller. Shaller had forward facing controls and I think they stopped production of the KV line in 69 or 70. All the Hofners after 1970 have top mounted controls, so.. it may even be a 69 Schaller. It's been recovered so no badges on it and I can't find any other identifiers without opening it but I'm too busy right now.
I'm pretty sure it's a tube preamp from what little info I could find.
Please let me know if you find anything.

Re: A 1970 hybrid amp
I haven't even really looked, it might. I haven't really had any time to check it out. It was in the pawn shop for $300. Ii plugged it in to make sure it powered up, it did so I offered him $200 and he hemmed and hawed until I was walking out the door and then said OK I'll take $200.

Re: A 1970 hybrid amp
It looks like this.

From what I can find out 69 & 70 were the only years with the staggered speakers. I'm not sure if shaller stopped making them in 69 or 70, so... When did Schaller dump all the production on Hofner?.. was it 69 or 70?

Re: A 1970 hybrid amp
When Schaller was selling them they were all tube, around 1969 is when they decided to stop I guess. The 69 Schaller and 70 Hofner look alike with forward facing controls. After 1970 Hofner sold itwith a different configuration and the controls in top as well as the speakers level and not staggered.

In that reverb link you posted. Shows lots of transistors (not that that’s a bad thing).

Re: A 1970 hybrid amp
Some of the things I've read and the fact that it turns on quietly but pops loudly when turned off and takes 30 seconds to power down.

Sounds like a tube rectified circuit with no standby. Old VOX’ do that.

Re: A 1970 hybrid amp
So far this is all I can find and it looks like it's from 1971

Is it solid state?
