Valve tester adapter question
Greetings! I mainly use my Hickok 539A valve tester to test my radio/tv valves. I am currently restoring a Bush DAC90A valve radio. The valve test data for the Rimlock valves (B8A base) states to use the 'Hickok adapter code 1050-129'. Nobody in the US seems to know anything about this adapter. I was hoping someone in the UK would have some information for this adapter since Rimlock valves with the B8A base are much more common there.
Regards, RCARADIOLA Donald |

Re: Valve tester adapter question
I am not sure about Hickock, but for early Avo testers I believe that the adapters just had a suitable plug that went into an octal socket and wired pin 1 to pin 1, pin 2 to pin 2 etc, on the new socket. Have you tried this 1-1, 2-2 etc wiring and seen if it works using an existing socket?

Re: Valve tester adapter question
I made a series of adaptors, using the principle described by Jeremy, to plug into my Weston TV-4A/U tube checker, and it works very well. The only problem is obtaining the test data for setting up the valve tester...

Re: Valve tester adapter question
Jeremy, Phil: Yes, I read an article pertaining to this. I just ordered a couple rimlock B8A sockets and will give this a try. I do own a Funke W16 Wehrmacht valve tester (1938) that has a B8A socket. The problem I have is that I don't have the cards for the DAC90A valve types.
