Matt: I think your best source of information that goes well beyond the schematic is at K4OAH.com. Garey is now SK (Feb 2018), but his wife Carole is still selling Garey's "CD's", which now come as

While not a Drake, But has the same effect. On my SB-220 I put those small verniers on both the Plate and Load. I'd hate to tune the amp without them. Even manually never mind "By The Numbers" Joe

As to straight cable, I've used the cable from Heil with success for years.

John, Be cautious about cheap quality import cords as well as local cords that are stiff. 73, Evan, K9SQG

Oh... And these are straight cables. Coiled cords are much more expensive and harder to work with. W7RY -- Thanks and 73, Jim W7RY

Any modern microphone cable will work fine. Its 2 conductor (red and blue wire) with a shield. Just like the 444 stock cable. Its also the same size. Easiest way is to by a mic cord with XLR

The rubber insulation is cracked. Would like to continue to use the mic as it still has great audio. Appreciate any recommendations on sourcing a coiled cable to match otherwise straight cable ok.

Hi All, Does anyone know where I can download PDF versions of the manuals for the T-4XC transmitter, R-4C receiver, MS-4 speaker, MN-4 antenna match and AC-4 power supply? 73s VE3MXG Matt

It's too bad Drake did not use a 6:1 vernier on the LOAD control. They also should have used a? 0-100 across the top 180 degs of the panel marking.? ?Done that way...it's just....'dial it up by the

Rob, To get a signal out on the band, you do need two things.? The PTO and XTAL oscillators need to be on, and the V3 mixer needs to be on.? You have correctly suspected these. I don't know for sure

Try adjusting the antivox gain. Steve Wedge, W1ES/4 Time flies like an arrow. Fruit flies like a banana. Sent with [Proton Mail](https://proton.me/) secure email.

Yes. These are the lamps? I was talking about.? The leads on the replacement lamps "might" be long enough to drop the front panel and not have to unsolder the lamps.

No, the rig is not transmitting - no bias current shown - it is defenitely in standby/RX mode.

My L-4B tuning vernier drive fix will appear in the March issue of QST in the Hints and Hacks column. ?As an aside a source of vernier drives and surprisingly some red pointers for two different size

Update:? I connected my other T-4XC to the setup and discovered that pin 7 of Mixer v3? of my other rig is 240 Volts in stand-by (RX) mode.......? I swapped the 6AU6 but to no evail.? WIll

Is perhaps VOX being tripped ? Is there bias current showing on the transmitter meter? Hopefully some smart people will be along soon with better questions :-) John wrote:

Hi John Thanks for thinking with me. Yes, I have another one, a Sure, but that is shortened when the PTT button is not pushed. Then no signal in SSB is generated, however when switching to AM of
