JL2,
Thanks!

Wow, she's a stunner! Is dennis going to leave that Sophia mesh plate in when he ships it???? Look forward to hearing how the rolling goes with his amp's.

Hi all
Quick question. Can I use the 5ar4 rectifier with the KT66 output tubes?
Seperate question, does anyone know anything about the 5gk20 rectifier?

That copper looks killer! Congrats!

According to Peter's notes, no, you will need a 5U4 rectifier to run the KT66's.

5 watts per channel - 6V6 output tubes and 5Y3 rectifier tube
7 watts per channel - 6L6, KT66, 5881 output and 5U4 rectifier
10 watts output - KT88, EL34, 6550, KT99, KT120, KT150 output and 5U4/274B rectifier
12 watts output - KT88, KT120, KT150 and 5AR4 rectifier

Just scored a NOS EML 5u4G mesh plate on the Ebay for under $100.00!

Between that and the Full Music 6SL7 I got from parts connection bargain basement sale for $35.00. I've got some fun tube rolling in my future! Look forward to hearing the Penta KT88's in the lil 6V6 amp. Dennis told me through email that he designs the circuit to run them with the 5Y3 rectifier. Odd he doesn't advertise this combo.... maybe its not ideal but he termed it as a "hifi spectacular" setup..... Wonder if that translates to overly bright with limited bottom end..... We shall see!
One week to go!

Tubes collection to roll;
Driver:
NOS RCA Jan6SN7GTB (from Dennis)
EH 6SN7 Gold cryo
Shuguang Treasures 6SN7/CV-181-Z
Full Music 6SL7

Output:
6V6 Gold lion Reissue(from Dennis)
EL34 SED winged =C=
KT88SC "preferred series" (penta)

Rectifier:
Sovtek 5Y3 (from Dennis)
5U4G SED Winged =C= Black plate
5U4G EML mesh plate (2010 old version)

I'm no longer sure about this. Those combos are what Dennis put in the listing for the KT120/150 amps. He doesn't seem attached to matching those up exactly though in general conversation. These are also different amps aren't they (KT66 vs 120/150)? Still don't know if some tube combos apply across these designs though.

Simon - nice selection to play with. Been running the Winged 'C' EL34s in the SLI 80 and have been very pleasantly surprised at their bottom-to-top presentation and have picked up another set for that 'rainy day' when no more W 'C' tubes are available.

So I received this from Dennis last night, it is specific for the 6V6 amplifier. Interesting that the KT90 is able push that kind of wattage! He also confirmed that the EML tubes work fine in his amplifier circuits as he has an EML 274B mesh plate himself. Looks like its hard to make any catastrophic errors with output tubes / rectifier tubes in his designs
