 Drake L4B amp with PSU  
Up for sale is my Drake l4b with power supply. I acquired it from another local ham and decided I wasn’t ready for that much power. Nor did I realize my breaker panel didn’t have room for another 220 breaker. The amp has upgraded fan unit. My loss. Someone else’s gain. Just needs a exciter cable. Buyer pays shipping. Txt msg preferred. Calls after 9pm UTC or 5pm est asking $700

  FLEX PGXL SN: 9-360/23-0107 correction
The PGXL was purchased from the original owner W6KW a super nice gentleman and very knowledgeable ham. According to an email from 403A it was manufactured in September 2023 (correction from original ad) I bought the amp in January 2025. It was originally used with my ICOM IC 7610 and Palstar HF AUTO tuner. Then it was used with a FLEX 6600 with a TGXL (also for sale in a separate ad) It was taken out of service in March when I sold the Flex 6600.
Excellent - Mint condition.
$4,695 shipped. I will also drive a reasonable distance to meet the buyer.
If you buy the TGXL listed I can offer a discount.
you want some pics I'd be happy to send some.

 FOR SALE: COLLINS 30S-1 AMPLIFIER  
$800 for this classic amplifier. It comes with manual, and two tubes, 4cx1000A and 4cx1500B. Amplifier works. In the CW low power mode it will put out 1000 watts PEP, more in SSB mode. Sometimes I do notice a burning smell but it goes away and it still works. It may be the fan. $800 with both tubes is a good deal. Pick up only.

 Amp Supply LK-500ZB  
I have for sale my Amp Supply LK-500ZB. The amp works perfectly on all bands and all meters and controls work. Cosmetically it is very good but please note that the previous owner drilled a hole in the faceplate between the grid current meter and the band switch. I put a flush plastic plug in the hole (see photo).The amp runs a pair of 3-500 tubes and is capable of 1200 to 1400 watts CW when wired for 240V. It is currently wired for 120V. I don't want to ship the amp but will meet someone a reasonable distance from my central NJ QTH. A copy of the instruction manual is included. Asking $950
