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.
I think I have some very nice nos tubes here but need to find data on them.
I have 13d3,s and the data, and these sound superb, I hope the 13d5's could be as good or better can anyone help with the data on these tubes?
I have a memory of seeing data which implied that the Brimar 13D5 is the equivalent of the Philips/Mullard/etc ECC85, which is really for use as a cascode in radio circuits, but I can't find the source yet. I'll keep looking.
