Univox 1061 PI Type?
« on: July 02, 2011, 08:50:35 pm »
Im thinking of grabbing this amp from someone. What kind of PI  does this amp have? Seems like the plate resistors are missing on the 12AU7 PI tube. I have not owned this amp before. I know nothing about it other than it probably has some nice old iron

PI looks like it is a DC-coupled cathodyne. Plate resistors are there but the first one is missing a value (probably 100k).

Thanks VMS. Do you have any amp projects going?

I have tons of amp projects, but unfortunately only on paper.

I do have one project that I think I'm going to build soon. It is this 1x10 speaker cab that I converted into a small combo. I only have to decide what to put in there, right now I'm thinking a Vibro Champ Reverb-Amp but that will probably change more than once before I order the parts.

A Univox 1000 landed on my bench yesterday.  I't is loaded with those paper in oil, grey color caps. They like to get leaky.  This amp has a long tail PI but simular tone stack.

I think im going to pass on the amp. I would be recaping 2 amps for it in trade. I have enough work as it is and enough amps too. Still has that Nostalgic Univox retro look. Am i crazy? Dont answer that
