That amp looks use the Ohmite 500ohm/10w resistor with the capacitor kind of hidden next to the first filter cap. Just caught my eye as odd but do like the 5881!

Measure the actual value of the cathode resistor with the amp off and carefully measure voltage drop across the resistor with the amp on. Check the cathode to plate voltage (pin 3 to 8).

The PT is looking to be delivered next Friday. Looking forward to firing it up!

Orderd up a chassis and transformers and got some time to start putting it together this weekend. Added an adjustable NFB and selectable output impedance. Still waiting for the PT and then will have to…[Read more]

It’s hard for me to determine the value of each from the photos, I suppose they could be different from the schematic.There is a minimum of space for that 10k between filter caps so maybe they moved/combined those to utilize a larger wattage resistor. I’m pretty sure that Fender used a 10k 1 watt carbon comp but that was with the 6V6 and…[Read more]

I do see what you are saying but my confusion is this. The builds in the images appear to already have a 10k and 68k between the nodes on the filter capacitors as shown in the schematic. Unless one is bypassed it would seem as though there is one extra 10k resistor.

Recently joined the forum here as I am considering a Two-Stroke type build. In looking at the schematic and comparing images I see that there is what appears to be an additional high watt resistor on some builds including that in Dave’s book. I have searched around a little but have not located any mention of this in other…[Read more]
