What year is this 120?

Post by Walls of Sound » Tue Oct 22, 2019 11:55 am

So its serial number is 120618 with a cab number of OA 3110. I found serial number 120493, and 120596 which are both pics only. Is it a 1972? Thanks, John

It is probably 72/73.
It has the pix only type circuit board (with board mounted preamp valves)
The transformers are Parmeko (I believe except the OT is obviously a replacement.
73 more likely as there is no mid-lift inductor and the front panel is pix and letters.
the green Plessey mains cans also suggest 73 to me.
Happy for someone else to be more definitive.
Probably needs to have a bias pot added to help give those modern EL34s an easier time, what is the output anode voltage and bias at the moment?
