Let's talk tubes...
I spent some quality time with this receiver next to my Heathkit TT-1 mutual conductance tube tester.
Unfortunately...nine of its 22 tubes test bad (extremely, extremely weak). A real shame, because until this afternoon it still had all 22 of its original Fisher branded tubes.
One of the nine is the 5AR4/GZ34 rectifier.
One 6AU6, two 6AQ8/ECC85, one 6AJ8/ECH81.
And...naturally...all four 7189 output tubes. $$$
Mike (morzh), a question. What's your feeling on 6П14П-ЕB (6P14P-EV) Russian tubes? And Sovtek tubes in general? I've already been looking at Jim McShane's site, and he recommends Sovtek EL84M while mentioning the 6П14П-ЕB as "well-known, well-liked, and now scarce". While I will most likely buy a matched quad of Sovtek EL84Ms from McShane, I see that I can get the 6П14П (no mention of the EB, does that matter?) for less $$ from Russian and Polish sellers. Your thoughts?
