Was, Wondering if anyone has had the PA transistors replaced? If so how did the Amp perform after replacement?. Was the replacement icom parts? The original finals are still available, albeit expensive. If you treat the amp correctly, and set the ALC like the manual says to the ALC is part of the protection schemeit will last a daga long time.
I own two 2KLs, and the one that gets nearly daily use is original, 2xc2652 the finals, and was purchased new in ! K0BGAug 19, There is two 2kls listed on Ebay. Seller states watts output.
2SC – TOSHIBA – Module – Kynix Semiconductor
He originally listed them as watt amps. I emailed him asking if they ran as with per Icom specs. He answered “he didn’t see why they datz. I believe they have the MRF transistors installed.
I know they will not work properly in my 2KL. IMD ratings may also suffer when the amp is operated beyond rated levels. Run conservatively and within specs it’ll last practically forever. Something will eventually go up dafa smoke due to the PA device ratings being exceeded. As far as the 2sc22652 being a replacement for the original Toshiba RF transistors is concerned, I ran across some info on this a while back.
Let me dig it up if someone else doesn’t.
N8YXSep 2, The truth is closer to watts PEP. I have two 2KLs, and neither one will put out anymore than PEP no matter cata hard you drive them.
The 2KL uses two modules, and each one has two 2SC finals. A quick scan of the data sheet on the transistors will confirm their maximum safe operating level. My older 2KL I bought inand it is still on its original finals—which proves that moderation is a key ingredient. By the way, the power supply will deliver close to 25 amps before the protection scheme shuts it down.
At 25 amps, the voltage sags to 40, or 1, watts input.

ddata Again, that’s 1, watts input. The bottom dat is, they guy is a gas bag! K0BGSep 2, The technician says my 2kl needs an lpf board that 40 caps are burnt up. Amp only works from 20 meters and up. Anyone know wher we can find an LPF board? W9GBSep 3, N8YXSep 3, Scott at Mts is putting in icom parts in the LPF board.
