Hi all, here is the second installment of this project where I get together the parts.
In this I:
1/ wind the power, output transformer, filter choke.
2/ form up and test for capacity a set of chassis mount electrolytic capacitors.
3/ mock up the output amplifier and test the ultra-linear output transformer.
4/ plan and bend up a chassis from scrap chook shed gal sheet.
5/ clean up various parts for use.
6/ Assemble a "Kit" of parts to assemble.

The 3rd and 4th parts of this saga will be assembling the set and making it work and making a cabinet and speaker box.

Cheers, Fred Lever.
