Just finished up a build on a TS500. Just one major misstep, (mistakingly-swapping the power transistor and the voltage regulator-thankfully, I spotted it and was able to correct that)
It all seems to be working and sounding amazing!
I ran all the tests and just wanted to post the results to see if it all seems within spec.
Power check V+ 15.99V
V- 15.85V
Clip LED comes on at about 6.85V on my multimeter. (at 6.5V on my meter, the last led won't light even with the trimmer all the way clockwise)
1K@.4VAC tape sat left 10.38V
tape sat center 8.33V
tape sat right 7.63V
40HZ@.25VAC 7.5ips 10.61V
15 ips 9.88V
30ips 8.79V
60HZ@.25VAC 7.5ips 8.73V
15ips 10.74V
30ips 10 V
80HZ@.25VAC 7.5ips 6.24V
15ips 9.13V
30ips 10.59V
Bias on Right 7.34V
10K@.25VAC 7.5ips 1.41V
15ips 2.37V
30ips 2.93V
Bias on Right 2.95V
Now off to build a second one!
