Finished a Crack. First, a stock Crack. Lived with it for a little while. Listened, acclimated myself, did a shake down. All's good. Sounds/sounded very nice stock. Then, installed the Speedball C4S. Yes, better, and in just about every way.
I would appreciate some others' look at the test voltages I'm measuring. Mostly, two meaures are notably different from the bogey values. From the assembly manuals, I read and understand there can be a fair bit of variance. The Crack + Speedball seems to otherwise be performing very nicely. It's Crackin' fun.
Here's what I've got:
Crack tested voltages.
Wired for measured house mains voltage of approx. 118-119V AC.
Tested voltages, PT-10
1. Terminals 7 and 9 = 5.99VAC. Manual, 6.5V AC ±20%.
2. Terminals 12 and 11 = 167VAC. Manual, 175VAC ±20%.
Tested voltages, Speedball
12AU7
1. OA, measured 80VDC. Manual, 60-90VDC.
2. IA, measured 180VDC. Manual, 170-270VDC.
3. B-A/B, measured 0.5mV DC. Manual, 0VDC.
4. IB, measured 180VDC. Manual, 170-270VDC.
5. OB, measured 86VDC. Manual, 60-90VDC.
6080
1. OA, measured 112VDC. Manual, 75-100VDC.
2. OB, measured 109VDC. Manual, 75-100VDC.
3. G, measured 0.5mVDC. Manual, 0VDC.
4. B+, measured 180VDC. Manual, 170-195VDC.
Anything to note about the OA and OB measures, both being higher than the manual's bogey values?
Thanks!
