A vacuum tube-born radio with loads of solid state mods ?
Sorry but then isn't a vacuum made receiver,transmitter, twin line ( etc ) anymore. The FUN about those "boathanchors" is "use it as it is". If i wanna something improved...ill buy a new product. At my side, the challenging while using old stuff is fun, fun and fun. The battle against big, closed, splatters while you have to fight with the passband tuning AND rf gain...etc etc. It's like to drive a Jaguar, but with a (eg) Bentley engine inside. Do we can call that car a Jaguar ? I don't think so. So, at my side, a Drake product, with plenty of solid state things inside...isn't a Drake anymore. Obv it's only my opinion.

The complete mods really puts the R4-C ahead of the pack. I have done 2 R4C's this way and wouldn't hesitate to do them again. In terms of individual mods, then the power supply is a must and perhaps the filter capacitors at the same time. The audio module gets rid of the class A audio amp which is a heat generator and source of PTO drift. I believe you would need to do the audio mod if the power supply is upgraded. So once you start you might as well keep going.

Which are the best to do? I don't mind how far I go with this, I just want the best receiver for my money, I would like it for Top band use but I know it will be good for all frequencies however 160M is where I want to go. 73 Max M0GHQ/W8BX
