My Centurion 422b amp is sick. With initial application of power, in selected PTT and STANDBY modes (and un-keyed), the 3-500's are drawing 140 ma plate current (and barely perceptible grid current).
Forgot to mention that I also meggered grid-to-cathode, plate-to-grid, plate-to-cathode at 1KV on both 3-500's (cold). Both passed. 73, Allen--W7GIF -- Original Message -- Sent: Sunday, February 21,
Duane, Andy, and Carter: Wow. Just confirmed that the TO-3 bias transistor (MJ15001) in my 422b is shorted collector-to-emitter. Admittedly, 4 failures isn't a huge sample, but it sure suggests that
Gary, No problem here. I have a built-in autocorrect "uncorrector". I read "overcurrent" despite the autocorrect's corruption. I'm inclined to suspect the failures are due to a device mfg quality iss
Just completed an internal visual inspection of the failed MJ15001 using a 20X stereo scope with alternate light sources. Unfortunately my "shade tree" failure analysis/forensic lab doesn't include t
With installation of the JANTX 2N3055 completed, and three full days of on-air operation, the amp is performing beautifully...tube bias problem solved. Pre-test of the '88 date-coded JANTX 2N3055: hf
My 565 Orion has the A14 autotuner, which has no battery. Although the manual calls out a p/n 81956, the A14 board in my Orion carries only marking: "LDG RG-11". Did TT equip Orions with (at least) t
Tony, Before you remove all those torx-head screws...my 565 has the LDG RG-11 autotuner which has no battery. Allen--W7GIF -- Original Message -- From: Tony Lelieveld<mailto:va3dwi@gmail.com> To: Dis
Hehehe...that's just what I did after the first R&R...&R. I'm glad that I'm in good company on at least one account. Allen--W7GIF -- Original Message -- Sent: Saturday, January 16, 2016 5:14 PM Subje
Oops. The LDG part/model number is RT-11 (not RG-11). I'll blame that one on clumsy fingers. Allen--W7GIF -- Original Message -- Sent: Saturday, January 16, 2016 4:55 PM Tony, Before you remove all t
You might try KE9PQ who frequently lists Paragon subassemblies/parts on a large auction website. His email can be found on QRZ. I have no affiliation with KE9PQ or his operations/business. Allen--W7G
Might be worth checking with Gary Follett W0DNV...on both counts. I recently got got a "no longer available" ORION VFO encoder from him...priced right, shipped well and quickly, and 100% functional.
Oops. Gary's call sign is W0DVN (not DNV). I'm not really dyslexic...but, confess to carelessness with the keystrokes. Allen--W7GIF -- Original Message -- From: A R<mailto:raf_3@msn.com> To: Discussi
The Corsair II was equipped bare-stock with two 8-pole 2.4KHz filters: One in the 9MHz 1st IF (on the 81252 XTAL FILTER board), and One in the 6.3MHz 2nd IF (on the 80979 PBT board). The 9MHz cf 2.4K
Carl, Is that really true? Aren't the 218 and 219 employed as roofing filters in the 1st IF, and isn't the DSP BW control in the 3rd IF? If strong adjacent (and/or dirty) signal conditions warrant ti
Thanks to all for generously sharing your knowledge. That generosity sure adds to the enjoyment and satisfaction of Ten Tec ownership...and the hobby itself. Tnx agn es 73, Allen--W7GIF -- Original M
Does anyone have a TT overvoltage crowbar kit for a 252/262 PS that they never got around to installing? Haven't checked for availability from TT, but have to believe they're LONG ago obsoleted and n
