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.

Thinking of running some AM on the Drake.
Have a T-4XC and L-4b...
Suggestions please from those that have done it
Hi Lee,
One immediate comment you'll get from the folks you work is that your AM signal
will sound like you're using
I have investigated the Sherwood Mods somewhat, but I found, like Steve
mentioned, a lot of it is directed toward building a better contest
radio. The mods really go after the close in IMD spec in CW. Other
than a little better audio, it seems that UNLESS you truly want a
contest rig, it may

I once used my C-Line with a single 500Z Ameritron AL-80. It produced about
100 watts of carrier and peaks of 600 to 700 watts. You really need to have a
scope inline to check the waveform as to not over do it.

HI HI. This subject is
I'll third it.
If I want something to act like a new whizbang radio, why not get a new
whizbang radio?
The joy of an old piece of gear is it being an old piece of gear that still
works well.
I suppose the ultimate update would be to remove everything in the
cabinet of a R4C and install
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

To Mod or not to Mod has been an interesting theme to close out the old
year, that is for sure.
Happy Old Year to all,
and may the new year bring excellent propagation, low noise, and resonance on
all antennas and remember, to tune is to exist.

The audio amp in the stock R-4C is already solid state. The Sherwood mod for
the audio amp does make it sound better and removes the big heat source right
below the PTO. That is the only Sherwood mod I made, but I'm considering the
power supply mod. I also installed the Hayseed Hamfest cap

I hate to tell you this, Adrian, but your Drake already has solid state things
inside.

Well I will say it just like my two 56 chevys one bone stock plane 235
inline six with three on the tree to my Loving hot rod with a 383 stroker and
nitros injection. the best of both worlds. as to Drake I have a plane Jane
B line , a plane Jane C line and a hot rod fully moded R4C
Hi Darryl:
I like that approach. No question that the mods make the C a better
radio. As long as a person understands what the final product is going
to be, then go for it. The performance margin that the Sherwood mods
offered over comparably priced SS rigs of the day is no longer valid.
Curt,
Well, certainly a vaild staement in general..BUT.
The r-4c Sherwood is still quieter than my 746 PRO was and my TT Orion
II is.
Still kind of like the analog dial too...very fast to move or very
slow...all without any buttin pushing.
Every now then...I will ONLY use my C line and L-4B

Lee,
That's a great idea since it gives you the opportunity to re-visit the older
technology and compare notes against recent designs. I have no issues with
well-designed and implemented mods that serve an
Personally I would never consider modifying my Drakes. They work great as is.
When I want 2011 technology, I use one of my modern rigs. When I turn on my
Drakes, I want to experience a Drake rig, and not some cobbled up one. I no
longer would consider buying any Drake rig with

Huh?
I don't see any of the MODS I have on my Sherwood R-4C as roll your
own...I guess if you can design and build printed circuit boards and
get all the parts including those neat front end filters you could.
Another way to get a Sherwood r-4C is get one from someone selling

Sure, why not? That's
One needs to look at these changes for what they are, in the context of their
original use when they were introduced over 30 years ago. Back then, these
mods did make a fairly-new radio perform much better. I can also remember ads
in QST for solid-state tube replacements. I never saw any

Of course anything can be done...it takes MANY, MANY hours just to
install all of Sherwoods mods even if you get the kits from him.
Then there is a modified alignment procedure too. (according to Rob, I
have not had to do one since he did mine)
Why invent the wheel...but as they say...go
Steve,
Have you ever had/used extensively a properly done Sherwood R-4C?
I have a TT Orion II right beside it.that's a pretty good
comparison machine, as would the K3...
I had the Sherwood before the O II...now I really don't need the
Sherwood, but I love it and it's staying. Sometimes I
Sartori Associates also made the kits available. The earliest ads I have
for the Sherwood / Sartori kits is 1982. Most of the articles for R-4C
improvement show up in 1979 issues of Ham Radio and 73. Fox Tango also made
switchable 1st IF filters kits available they called GUF-1 and GUF-2.

Maybe you missed the part about FUN! And the sense of accomplishment.
Parts are cheap.
