Don't know yet

Schematics printed incorrectly in guide which lead me to wire incorrectly and I toasted my output chips. It was easier to order new boards than try to desolder. I have been stuck for a couple of months waiting on my new set of matched output transistors. So started in August and now November and I can't give useful review. Just reminding folks the schematic has all chips 240 but really mix of N and P with half ending in 9240 and half 240. It is printed on board correctly. I am embarrassed I missed give push pull and not single ended. The boards are beautifully made. The mouting holes matched up perfectly and installing on Deluxe case went flawlessly. Might suggest leaving one of the 3 watt output resistors high enough to get some alligator clips to simplify the process of setting bias.

Beautiful Amplifier

I`ve built an BA-3 Amplifier with the BA-3 Frontend and the Complementary
Bias and Output Set.
The sound is super clear and detailed. But not too `cool` and `over-analytic`.
A very good brother / sister to my F5-T.
The boards are very good quality. Super fast delivery. The `baby`was easy to adjust.
Sorry! No more words - I have to listen to some music :-)
With full respect: Thanks `Papa Nelson`
