Re: original diagram here
Thank you aardvarkash! This, once again, goes to show that this website is a real treasure. For days I had been unsuccessfully searching the net for the original diagram...
I wanted to take a look at the schematic in the first place in order to find an info on the output transformers - 3.5 Ohm speakers were connected and that's what confused me... Since I'm new to tubes and without any diagnostic equipment whatsoever (save for a cheapo digital multimeter), I couldn't measure the primary load...
Further, it turns out the mono RtRs were not EL3536 after all (I was careless enough to throw the decks away without writing down model numbers). They have EL3536 output transformers - WT 511 22, but the power transformers are WT 510 92 and WT 511 13.1 - different numbers but with identical pin layout and both with EZ80...
Another model, though - EL 16B, perfectly matches the parts layout...
And as to the RH EL84 - I've built one and I'm extremely satisfied with it. Hammonds, no PIOs and no tantalums and it still sounds quite nice...
