GZ34 filter question

[ivan H]

Hi, I built like a JTM50 transitional amp using 1202-55 PT & 784-139 OT (EL34's). I've been using a SS rec with 50+50uf main filter, all others 32uf. To use a GZ34, should I change the main filter to 32uf or is it ok to leave it at 100uf. (I know it'll sag/compress more with 32uf). I'm just thinking whether 100uf would strain the GZ34, as I know 2 x EL34's already will when cranked. Any input appreciated. Cheers

You are correct you will kill your GZ34 in short order.

As a rule 64uF is the highest you should go (I quite like 48uF 16+32uF can in parallel).
