WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
Building, troubleshooting and testing of these amplifiers should only be
performed by someone who is thoroughly familiar with
the safety precautions around high voltages.
TnX. for the link.
I take it that RCA is equal to Ediswan, in every aspect.
In the PSE><TPP thread, am refering to a EDDA amp.
Originaly equipt with ecc86 Ediswan, replaced with el84 mullard.
Some rewireing must have been done.
