What he's missing in his head is the fact that power out does double as the plate voltage increases only by 1.414 while the plate resistance stays the same. This used to flummox me, too... then one

I use strip LEDs fully across the top of the 2 meters. ?No problem with RF. ?Run the wire to the 12v rail on the meter board and ground. Sent from the all new AOL app for iOS

Wow, great info from both of you!! lou, do you still have any of those power supply boards for sale? Sounds like something handy to have. I had read about the power supply being in that air cooled

Thanks Lou! placing lamps above the meter is where they should have been. I don’t mind the extra work taking things apart and spending time doing a job. I love working on projects with the Collins

Hi Louis, Thanks for the suggestion. I didn't realize dropping the rear panel was that easy. I hope I don't have to go through this again, hi! And, I did get one of your PS boards for the future, it

On all the HF2500 amps I buy or repair for customers I install strip LEDs above the meters. ?I don’t want to mess again taking the amp apart for meter bulbs. ?The originals are fuse type bulbs.

Justin, I have a couple of HF-2500 amplifiers I've used for many years and experienced the same failure of the meter lamps. The earlier HF-2500 (single meter) has two bulbs and the later (two meter)

Hello, I have a Commander HF 2500. Have not had it to long. When I got it, only 1 of the 4 meter bulbs was working. After about 3 month, the bulb went dark. I believe there is a 12V 1A regulator

Hello. I'm 76 years old. I are in my L7 ! I will use a bridge rectifier circuit with 4 x 866A/3B28 tubes. I think you're making things a lot more complicated on this point, even though it's nice

Hi all, My b-i-l suggested I join this group and seek comments.? My age is 75 & I've built electronic stuff for the past 60+ years.? My "ham Elmer" had a Globe Tx with a 4-250 modulated by 2 x 811's

Fully operational and wired for 110V operation, has latest firmware version installed. $2500.00 shipped to any US destination (Buyer pays add additional insurance if desired) Includes a 6 month

What does this mean? Your comment makes no sense. The link provided (to FCC) is for comments in regards to GMRS rule making, not the traditional 11m citizen's band. -- 73, ~Alan

Hi All, I've been looking to buy the 10-meter mod for my Ameritron ALS-600, but all the major ham vendors seem to be out of stock; I suspect that it's not being made anymore. Does anyone have one to

Dear Alan, Where in the world have you been? Didn't you read that along with the new No Code, No Theory, No Regs licensing there's been a lifting of the power limitations? From 26.0001 through
