Hello,that capacitor and resistor between the plus and minus output for the speakers; is this to secure the amp in case off running without output-resistance?
And, is this layout an example with or without feedback?
Thanks for the informations
Olaf

that RC on the speaker outputs is a zobel network... maybe intended to damp some ringing in the OPT. You'd have to ask the designer, or rig up a test setup and see whats going on. I think its unnecessary when using output triodes because of their low rp, but thats just my guess.
This layout has feedback (looks like a 30K and paralled cap.)... 24k was stock , IIRC.
