Does not surprise me...is it a supply that has had a full update
(Heathkit shop or other)??
If not I would do that right now. Everything in there is getting old.

A short in the B+ line within the T-4X will open the resistors. It used to
happen a lot when people would change the blue filter in S meter of TR-4’s and
pinch the wires reassembling the metal cover on the S meter. Look for a short
in your T-4X.

My T-4X quit working today, the 250V supply was gone. Filament, bias, and 650V
supply normal. On investigating the AC-4R board in the AC-4, found two

Ted,
I think most folks have indicated that it is normal to see power lower in CW
than in TUNE. But only 60 watts kind of sound like you might have a single
final out, or maybe both weak, or maybe poor filter caps in the AC4, or other
minor issues.

Before you start replacing parts clean the Band Switch contacts and reseat

Hi Bob:
Before jumping right to looking for a flaky component, have you done the
requisite re-seating of the board? Deoxit on the edge connector, and
relay cleaning?

I have a T4XC and in normal SSB the Gain control is around 9 O'Clock for
correct modulation. When I'm on CW for full power which is around 125 watts the
gain is about 3 O'Clock. Settings will change the higher in Frequency.

Normal. The GAIN control is two separate potentiometers, and they operate in entirely different
ways. In TUNE it's an AF GAIN control, in CW it's a bias control to unbalance the Balanced Modulator.

One thing that I have never understood, if the R-4any is the VFO in use
with the TX-4, and the R-4 has the crystals - say for 160, then is a crystal
needed for the TX-4? It does not seem logical because how would

The 160M 'Mod' consists of a couple of extra capacitors to stretch the 160M band down to 1800 kHz
rather than the stock 1840 kHz.

Hello Don and the group.
Please do not quote me but if memory serves me correctly the HC-6 and the FT243
have the same center to center pin spacing, just the diameter of the pins is
different with the FT-243 being bigger (as in same diameter as a pin from an
old octal tube or .093" od). Also
Does anyone have the "scoop" on this 160 mod on eBay? Yes, inside there are 4
crystals in the sockets and the decale on the front looks like a nice addition,
but what could be the "mod" ?
