 WTB: Collins 30L-1 amp OR Kenwood TL-922
Still looking!
Want: either emblem of 30-L1 wanted if clean.
OR
Want TL-922A.
Clean, working, few mods preferred. Need pix of insides and out.. List of mods. Tube type and age. Power out data and pix of plate voltage on meter. Time you’ve owned amp.
Only replies via QTH accepted. Need verifiable email AND phone number. NO SCAMMERS!
Prefer PNW so we can minimize shipping. All amp ads seem to be on east coast or MidWest and no one wants to ship. I’m willing to pay fair price for good working amp but may need you to ship on my dime. Lost out on a good 30L-1 due to shipping cost.
Gonna go the amp route as I just can’t climb towers anymore, so wire antennas with amp will be my future.
Thanks, 73,
Tim

 DIY599 PA500 Amplifier  
PA500 amplifier from DIY599 - made in Germany by DL4KA. This hard-to-find, limited production amp with a built-in tuner is very lightly used, indoor testing and only one day in the field for a SOTA activation. Item is in excellent, nearly-new condition. Non-smoking household.
$1,850 USD including insured shipping to the continental US. Payment via Venmo. Contact me at my QRZ e-mail.
More info at: http://www.diy599.com
Here is an excellent field review: https://oh8stn.org/blog/2021/07/29/diy599-pa500-hf-amplifier/
The amp has a built-in tuner and requires only 1 to 2 watts input for up to 60 watts output (20-60 depending on band and input from 0.5 to 5 watts). This amp is designed to work primarily with QRP transceivers. It is highly efficient in the field with current consumption at idle at 50-55ma at 13.8 volts according to tests by OH8STN.
As shown in photo, the sale includes a power cable with PowerPole connectors, cable for the Elecraft KX2, and for the Discovery TX500.
