Thanks. I'll do that next time I have a chance.
Electrical is a foreign language to me, so there is plenty to learn.

Yes, that's a good advice! Will implement that in my next (headphone)amplifier too.

Excellent work done ^ Congratulations El Sid

I indeed buy recently ~ 70 years old Philips BX690A in incredible clean condition. Great amazing sound quality with connected to the radio audio input TDA1541 modern DAC. It's my mono minimalistic sound system for romantic evenings in the summer , just for audiophile fun

Nice. Really enjoy the beautiful craftsmanship of some of the vintage things. Good to see someone with appreciation to keep it going.

Amp from scrap Except for power transformers, each channel gets it's own CLC filter. Apparently, I forgot to clean off the centre line marking.
