Re: Rigonda Stereo - Reviving the beast

Going back to tracing the coupling cap - I just thought that there might be a grid stopper (1k-ish resistor) connected directly to the grid pin.
EL84s (and most other audio output valves) do get quite hot - enough to burn your fingers quite quickly!
Don't worry too much about the blue glow - they sometimes did this slightly from new.
The chassis is looking good.
