Check that your carrier oscillator is at 5645 kHz. C6 is the ceramic trimmer on top of the chassis, right-rear corner area. If your CO is on-frequency, you could have a bad filter. Rare, but it

My TR7A still has the annoying feature of not going to no signal. Steve Wedge, W1ES Time flies like an arrow. Fruit flies like a banana. Sent with [Proton Mail](https://proton.me/mail/home) secure

Peter, Oops... I meant 6JB6A's. The NOS 6JB6A tubes I see for sale are never listed as "matched pair".... is that going to be a problem? Thanks for the screen resistor advice. 73 Jay W6CJ

My T-4XC sounds decent on LSB but very tinny and pinched on USB. How do I adjust this? I saw a reference to adjusting C-6 but I can not find a C-6. Where is it? Thanks, Ed KG5UN

I don't actually know but suspect they are the same. Pillow stuffing would work OK and is likely cheaper. Anything sold for audio seems to become expensive. -- Richard Knoppow Los Angeles WB6KBL SKCC

I've wondered if the Acousta-Stuf Polyfil is the same as the Poly-Fil pillow stuffing one can buy at Walmart? 73 Stan KM4HQE

Rob — I read somewhere that the last version of the SE-3, with the addition of the "AR" switch on the front panel, involved only the addition of the switch and a 100k resistor. Can you please

Later TR7’s did not suffer this problem. It seems the pot was changed to one which got to zero ohms before the click. Gary W0DVN

Jay: Couple of things.... Suspect you made an error about the final tubes. *6GE5*'s wouldn't fit as they are 12 pin tubes, with the Plate on pin 7 instead of plate cap like the original tube, a 6JB6.

The R-4C has the same problem. It may go clear back to my original R-4. Rob, NC0B

Dave, I shipped an R4C (with PTO and other issues) to WB4HFN, who reported the NB was not repairable - parts availability. Before shipping the R4C with the NB installed, I tried alignment from the R4C

Hello, I am? looking for the part reference for the very small lamps used to display the buttons pushed state (Ep, Ig, STBY, OPR, ...). Thanks you.

Peter, Thanks for the reply. I always use an appropriate dummy load to initiate a tuning process. Once I establish max output I switch over to the antenna and re-tune and adjust. The output is

Jay, I just took a look at the schematic and didn't see anything that would currently be unavailable except maybe the coils and possibly the socket for the blanker. What is specifically wrong with it?

I looked into the PA I damaged when a faulty key put the radio in transmit: - One of the parasitic choke leads popped out of the resistor. - One of the 1-watt cathode resistors is cracked and both

Looks like reasonable stuff. Will have the advantage over fiberglas that it won't get into your fingers. Fiberlas should be handled with fairly heavy gloves and a dust mask. Most hardware stores have

I have commented in this and other lists about the speakers sold for communication receivers. I won't repeat everything here. The technology to make a better speaker is not new in any way and can be

I have a 4NB noise blanker that Ron, WB4HFN said he was unable to repair due to parts availability. Is there anyone who repairs them? Thanks & 73 Jay W6CJ

Yup…One and the same, albeit a wee (sic) bit cheaper at your store Joe – W7RKN From: [email protected] [mailto:[email protected]] On Behalf Of n4buq via groups.io Subject: Re:
