The R-4C (stock) is hardly a true vacuum tube radio...very much a
hybrid.
Even the R-4B has quite a few transisters.
Early R-4a...= tube RX...and I'm looking to get one of those some day
(Dayton??)

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.

Max, if you are inclined towards doing all of the R-4C Sherwood mods on
your receiver then I would say it would be well worthwhile. 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.
Best of luck

I am thinking about doing the full works Sherwood mods on my R4-C.
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.
