EMUD Console/Lorenz Tubes

[jcmjrt]

I found an EMUD W. German console with a receiver. Not much for looks but I picked it up for $20. It works, but low volume. I haven't done any troubleshooting yet so I have no idea what's wrong. There was no schematic or literature. The tubes are 1 - ECC85 (6AQ5),2 - ELL80, 3 - ECC83 (12AX7), 1 - ECH81 (6AJ8), 1- EBF89 (6DC8), 1 - EAA91 (9AK8), 1- EM84, 1- EZ81 (6CA4). The tubes look in great condition with complete markings and all appear to be Lorenz. Anyone know anything about EMUD or Lorenz tubes? and ELL80 ouput tubes?

ELL80 is a dual pentode, push-pull in one bottle. Hope they're good - NOS will cost you $40 apiece! If you can find a model number, it should be possible to find info. If you CAN'T find a model, check radiomuseum.org (pictures and tube lists for MANY euro sets)

Capacitors are more likely to be a problem that tubes... but leaky caps can take out output tubers fast!

Hi Tom, Thanks for the link. Looks like an interesting source for info and I'm going to see if they need the telefunken schematics that I have. I had never heard of ELL80 before. I wonder if the tube checker that I use (at a local electronics shop) will have the info for the ELL80? We'll see. I wish that clean tubes with clean lettering meant good tubes....at least this time I do.
