I had a feeling it was in my interpretation of the three references combined with the variables you mentioned - that’s why I kept reviewing and looking for possible misinterpretations. I remembered that I was confused by those connections initially, so I figured it warranted some digging before tearing into other things.
As always - I appreciate all the help I get here to include the “passive assistance” provided by others’ build threads and pictures! Really invaluable to someone who lacks the basic theory knowledge (like me). I’m always learning from you guys.
This thing sounds great - and definitely different than my 102 or 2nd Gen - which was what I was hoping for. Just have to put the aluminum flat stock on the cab and that’ll be ready; but I plan on keeping it on the bench for a few days just to keep an eye on it. Also, I have to mention how I’m always surprised by the differences in preamp voltages dependent upon the given tube and position - and how they interact both voltage and sound-wise. Below is the combination I like today, lol.
I also tried Ian’s choke polarity experiment and found that it did make a difference in clarity and harmonic content. Subtle, but definitely noticeable. Now I have to check the other amps when I’ve got time.
Here’s where we’re at currently as it starts to break in:
B+1: 474
B+2: 473
B+3: 436
B+4: 349
B+5: 309
V1a: 194 Tung Sol 12AX7 long plate
V1b: 198
V2a: 221 GE 12AX7 long plate
V2b: 224
V3a: 275 Ruby/JJ HG
V3b: 265
V4: 473 plate/41 bias JJ 6L6GC x 2
V5: 473 plate/39 bias
FET: 17.4 - 7.1 (R1-18k, Rs - 1k6)
Thanks again guys
