Default Re: Philips 830C here we go....

Thanks guy's.

Not sure how to respond, hence the delay..

OK, so my original bridge rectifier design, the resistors got so hot, could not touch. Sizzling hot.

The design with the transformer is a lot cooler.

I think I have the 1928 model. The barretter is a UL28, I am assuming 1928

According to radio museum Type 1928: 190-260 Volt DC mains.

That's why I have tried to construct a DC voltage in that range.

I have not powered this up as yet.

When I received this set a single diode and capacitor where across the AC mains voltage.

Next issue I have is Valve 4..

According to Radio Museum should be a B 2043, when I received this set it had a 16v Cossor 0.25A valve. Which did fit nicely.

So bought a compatible valve type RENS 1823d, only issue with this is the side screwed connector, it snags on the side wall of the valve holder and the valve goes in squint, also I don't have a wire on this set to connect to this connector.

Makes me think or (thik), not sure if I have got this all wrong.

PS

I did a lot of googling re 230VDC supply there where not a lot of options out there. A few on Indian websites but nothing really concrete, hence why I tried my own design.
