Dynakit 70 filter cap question
Antique Electronics Supply carries an original style 525 volt multi
section can capacitor that will work and look like the original. Also,
replace the selenium bias rectifier and the two capacitors in the bias
supply with something like a pair of 50-100 uf @ 50 or more volt
capacitors. You should replace those original coupling capacitors as
well since they love to leak DC voltage from the phase inverter circuit
to the control grids of the EL34's.
