Hi Bob, Lou sent me a photo, and I am ordering a meter from him. It looks just great. No need for you to go to the trouble of taking a picture. Jim McPhee Placitas, NM W5ABA

Hi Bob, Thanks for the offer of a picture. I would like to see one. Would you post it here or send it to me? My email is jmcphee at comcast dot net. Jim McPhee Placitas, NM W5ABA

Hello Lou, If I’m not mistaken you were active on the Yahoo TL-922 list a few years ago, and we exchanged some messages. I looked for your email address in my Outlook client but couldn't find it.

Jim, I have one of Lou's meters in my 922. You almost can't tell it's replaced. Let me know if u want a pic. Bob W4JFA [email protected]> wrote:

A recent event of unknown cause or origin has totaled the existing plate current meter. I have replaced R5, R6, and R7 (R6 was toast). Diodes D2 and D7 are on there way and will be replaced upon

I have several of these modules, they all use the same tube so no worries there. The cylindrical metal piece the tube screws into is electrically connected to the anode, but the actual heatsink isn't.

The heatsink appears to be 50X the size of the tube.? How much stray C is that heatsink alone going to add to the circuit ? Whether it's the Y-685A? ?or any other tube, I would suggest obtaining at

I wonder if there are any shops that would rewind it? Bob W4JFA

Reid, thank you very much for looking that up. The info is greatly appreciated! Fortunately I still have the intact device that it was in, it was fully functional. The MCL 15222 generator achieves 100

Hi Don.? I wonder if you ever located one of these transformers.? I had one of those amps about 50 years ago and used it for years.? I see that Hammond Manufacturing, who bought out the Peter Dahl

Eimac history shows: 03/73 Y685A is an 8906XAL special, for MCL generator" the -AL suffix indicated a tube made for the Airlines, they used a lot of planar triodes in the past for short range

Dear Alek, Thank you for the kind words. Hal

Yeah, thanks Hal. You're a man after my own heart. I have been fortunate to be able to help others in a similar way over the years and I've also been on the receiving end many times. I've met a lot of

The YU-106 appears to be a just 3-4 wraps of 3/8"? copper tubing wrapped around the anode. The YU-191B? is the real deal, with the coffee can around the anode.... just like all the other water

Dear Alek, Read your quest for the power meter manual, and herein certainly wish you success. Some chap wrote me the other day, looking for the manual for a 10KW ATU that was only manufactured for a

This is a really long shot. I am looking for a user manual and more importantly, a schematic for a "Agikawa APM-1H" automatic SWR and peak reading power meter, 1-8 ~ 60MHz. One is pictured here.
