Hi LF

Thank you all for the reports

But the audio PA is a hell. The g= ood point is that looking at the results with this I can expect a very dece= nt signal when using 50w

and a clear output sinewave (cert= ainly not the actual sitiation right now)

Thank you for the PA recommendati= ons, Stefan and Andy. Will follow that paved path ! ;-)

For the output transformer I have= got a TDK 63x38x25mm blue ring core with N87 material. It was cheaper= than Amidon 240-77 and ready available

from Farnell. The AL value is 500= 0 which looks good

IRFZ48N in TO220 are also&nb= sp;in stock here. So will give them a try. Using the already available 13.8= V power supply for the MF PA is a good option too

So, we have: U3S with duble frequ= ency to 74F74 feeding both channels of 7667 and the pair of IRFZ48N. D= o I keep the RC at the mosfet drain ?

All the rest as in the W1YD schem= atic ? Less primary and secondary turns in the output transformer not= ed
