Well, I got a pair of NOS Sylvania 7236 matched for 60$, so that is 1/3 of the price I would have paid for TS 5998. And some Siemens E88CC with gold pins for 120 $. Hope that will do the trick. Are the rectifiers a must or is stock decent?
I can get some Ei EZ80 for 35 $ a pair.
The RFT EZ80's are great rectifiers and are cheap...can get a NOS pair sometimes for $20 on ebay.
