With a few other builds mid-way when the BeePree arrived (fantastically packed, all parts intact and as always - supplied with FANTASTIC documentation!!) it has been a few weeks before I could jump into it with both feet.
After a few easy evenings of soldering the preamp is done, passed the smoke test (phew!) and all the voltages are good (a few percent higher across the board, but I run higher than 115v by a few ticks most days here at the house).
SO - the smaller 8907 tubes are pretty hot to the touch - the heatsinks on the rectifiers are too (which makes sense of course) but are there some general guidelines about desired operating temps? I have an optical thermometer I use frequently with other projects, but a quick search of the forum and I couldn't find this one asked or answered.
I'm sure I'm being paranoid, but I'd rather not have to order new tubes or damage the rectifiers by not double checking.
One deviation from the measured specs is that on pins C4 and D4 (marked N/A on the voltage check) I'm seeing 6V. This makes sense based on the fact that these are the neg LV taps off the transformers, but I'd hate to omit a possible cause for concern.
Thank you in advance for any guidance,
