Paul,
It has taken a bit to time to get back to you.
I checked the 220 ohm resistors running from tube pin 2 and 7. The Pin 2 resistor tested at 216.8 but pin 7 resistor test at 258.4. I dug around and found a handful of 220 carbon comp resistors and replaced the pin 7 to the terminal 9 resistor.
Fired it up and fundamentally obtained the same results with -
IA=401, IB=402 (mains are at 123.5 - 125.0v), OA=389, OB=172. Monitored for 1 mins, no appreciable change. HLMP LEDs lit. Kreg(s) at 2.50. A silver lining is that I checked this with 3 tubes (including my original) and the reading are all close enough for me to declare my original tube as not failed !
Rechecked resistor and other connections just to be sure. No joy. So, looking for further guidance on repair advice steps.
Let me add, this was my first BH kit and my entry into "the journey" with tube based amps/preamps (2012-2013) and the build shows as I study it!. I have since built a number of other BH kits -- S.E.X. 2.1 with upgrades, 300 BeePre, Paramount Monoblocks (300b), Smash/Smashup, Reduction and a non BH design known as the DG300B amp (source your own materials) from a company in Canada providing PCB's, schematics and design documentation.
My point for sharing the above is I have been studying amps to support a 45 build, which as you can expect lead me to the Stereomour II. I have followed a couple of threads here on the forum and the path to getting that up as a 45 based amp. But I have been thinking maybe I leverage all the great gear, documentation, etc I have in this original Stereomour and clean up my "learning kit" build and bring it back up as a 45 amp (45's have been on my list for a long while now).
Love you thoughts here as I would strip this kit for the most part, leverage proven BH documentation, update appropriate parts that don't take well to resuse, clean up OPT and Power transformer (clean, paint), I have several of your wood bases (bought during one of your guys clearance sales in times past), lots of spare parts and access to all I would need through the interweb and so on.
Please advise what you think - specifically should we get this resolved first, replace the C4S which I am inclined to do regardless if I can still source that PCB from your spares/inventory.... or just get 'er back running and simply order a new Stereomour II and drive that to a 45 build --- but as an aside, I will say I have been holding out for the MonAmour 2A3 monoblock - which I have been on the notify list for a good while now.
Thanks in advance for all the consideration of the above and all the support you guys provide to this forum.
Cheers
Bob S
