I wouldn't call these NOS....people use the term to justify the inflated price of mediocre new production tubes. But hey at 18 quid each, maybe some people would risk it 2

oukouk Posted February 17, 2024 Posted February 17, 2024 (edited) @xlr8or @Silver Audiophile Gents, I found these locally.. Advise on the SQ of these please. I don't know when they were produced? do the numbers on them mean anything? regards V Edited February 17, 2024 by oukouk

I don't know when they were produced? do the numbers on them mean anything? regards V The good news about these tubes is they are very tightly matched for each triode section. Tektronix was a manufacturer of high end electronics testing equipment, including cathode ray oscilloscopes, which I suspect these tubes were used for. The bad news is the SQ of these Telefunken Berlin factory manufactured long smooth plate ECC82/12AU7's from the 1960's is pretty average sounding compared to other vintage types. I would recommend these tubes for use only in positions where very low noise or equal gain is required, more so for the V1 position in phono stages and line stages. 2

My ex phono uses 6x5 and the gec is the best I have tried. Some people say bendix 5852 the best, I tried also but so so.... 2 1

Thank you Kirk..Whilst I am at it.. might as well query these as well. Below are another 2 sets of Telefunkens - the code on them says "bi".. Do these have the same SQ as the tektronix as well?? I have a Primaluna pre-amp evo300.. (& A PL power amp as well).. Your advise on the placement please.. appreciate your input. rgds V

oukouk Posted March 17, 2024 Posted March 17, 2024 (edited) @xlr8or Hi Kirk, Appreciate your knowledge in this. Query regarding the silver patch (not sure what is this called) on top of tubes. This is a situation I'm facing at the moment. Tubes are GZ34. With Amp switched OFF - silver patch on top of tube looks good and shiny and you can see your reflections on it. With Amp swithced ON - silver patch on one of the tubes (1st photo) is becoming translucent, and you could see the through into the tube (not sure if I'm explaining this well!). The other tube looks normal. Appreciate your advise if I should be concerned. Edited March 17, 2024 by oukouk updated photos
