I’ve scavanged a number of old valve stereograms from the side of the road, these inevitably use a single ended amp. I want to convert one to a p-p amp (for guitar).
Is there a way I can use the existing op transformers (which have no centre tap)? I was thinking of using one for each anode circuit, but this site http://ozvalveamps.elands.com/optrans.htm says “You can't, for example, use one transformer in each anode circuit because both will saturate on unbalanced DC.”
I there any way around this? and can anyone give more detail on how this happens?
cheers,
Pete McK
