You're right, Eddy. I do prefer to remove the entire subassembly as it makes it much easier to work on.
I can R&R the front panel in about 10 minutes, I'm so used to it...

This is a good time to clean it as well as the fiducial window. Use only dish soap for the window or you'll take off the red line! Hi Guys, Well, I can not vouch for the "A" & "B" series, but in my T-4X transmitter that extensive a dis-aasembly is most assuredly NOT required... After removing the three tubes immediately behind the PTO can, the can itself is extricated by first dis-connecting the top grounding spring, & then lightly squeezing together the "side prongs" that hold the can in place, one prong at a time (this is by far the WORSE part of the operation, and the most time-consuming). The can is slipped off the assembly, rearward (where the 3 tubes were). Next, with a pair of long needle-nose pliers, each brass spacer that you see at the front of the vertical PTO board is grasped (so the spacers won't fall & get lost), and a slotted screw driver is used to unscrew the 4 screws that go through them. The PTO board & coil assembly is now loose, save for the 3 wires that are attached to the front vertical board: draw a simple sketch showing where these are connected so that you'll remember when you re-assemble everything, then touch each point on the board with a soldering iron to release each wire... The entire assembly is then slipped back off of the brass rod with the ferrite slugs on it. Absolutely no need to remove the front panel, no need for anything that complicated, or involved... To re-assemble, simply reverse this procedure! Hi Hi ~73~ de Eddy VE3CUI - VE3XZ
