Hohner Orgaphon OT

Post by Neonknight »

Hi All,
I have a hypersil output tranny of a Hohner Orgaphon 30Watt amp.
It was using two PL84 tubes at about 380-390V anode voltage.
Can anyone tell me what impedance did this PP stage need?
Did anyone built anything from the OT of an amp like this?
Thanks

This output tranny has 3k-3,2k primer impedance.
Does anyone have an idea what can I bulid with it?

Well maybe, just maybe you could do a 4x 6V6 amp, but i'm not sure whether it'd be able to stand that much... I guess it can, but better to be safe and hear an opinion from an expert - Also EL34s run on 3.4k, so that might be also an option, but again, i'm not sure about the power handling.

Thanks Bulatovic,

I have checked the parameters of the 2 EL34 with 3,4k on the duncanamps webpage.
The datasheet says it produces 35W.
I'm not sure if it is safe, but maybe I will try it.
