4-1000 Project: I have a 4-1000 HF amp that is 90% complete. It needs a filament transformer and power supply. It has a large roller inductor and vacuum variable. There is a tube shown in the picture but it is not good. Pictures will be sent to inquiries. It has a new Eimac air blown socket with chimney to blow the chassis. Also, I have parts for a power supply including a 5800 volt transformer rated about 1 amp, capacitors, diodes etc. Will sell all for $650. Located in Memphis, TN This would be difficult and expensive to ship.
