Changing Plate resistor question.

[daxliniere]

Here's the schematic for the Strauss SVT-H50R. See if it matches your subzero.

Hey everyone, just a quick note. The Subzero branded H50R has an 8R output and, from the schematic, the Strauss has 16R output. Resistor 27 (R27) is actually 56k rather than 75k as shown.
I suppose there may be other differences, but I'm yet to really dig into this amp.

Well, you may find minor differences, but main ones are visual ones (Tolex, grill cloth, etc.) and of course the silkscreened label.
