Beemer what you looking for specifically? The area in Pink? I googled 5Y3GT tube performance and there was tons of info...

They had one for GZ34's too!

Was looking for minimum input resistance of the 5AR4 and 5Y3GT. Really, the minimum resistance needed during cycling phases of the diodes. My understanding is the higher this input resistance --- the greater the total PSU filtering capacitance you can use.

Would have been nice to have all relevant rectifiers to today's amp, on the same chart. Then, you can see if interchanging tubes could lead to a long term issue.

I guess the manufacturer's tube data is the way to go.


Thanks! :mrgreen:
