HEATHKIT SERVICE BULLETINS - DX-60

[Brian Carling]

Great stuff Joe!

Anyone got any more DX-60 tips and mods?

I am having a blast with mine!

I picked it up for $20 at a hamfest last month and it just had a
burned 8.2 ohm cathode resistor on the 6146.

Works like a champ now. OK, the case is ugly but the front panel is
clean. Any more DX-60 fans on here?
