FS: Rm Italy KL-503HD

[NightThumper]

This was purchased 3/24/2021 from CopperElectronics. This is the. HD version (a little difficult to find these days). Brand new in box never turned on. Included with the amplifier will be a 120mm x 120mm fan with Anderson powerpole connectors and a 2.5 feet power cord with pin terminals on one end and an Anderson Powerpole SB50 on the other end. (10 gauge silicone tinned copper wire).

I’ve posted a picture of power output using my other KL-503HD. The pin terminals have been hexagon crimped and the powerpole connector has been “flood soldered” then shrink wrapped. The cooling fan is from my KL-703. I replaced the fans with higher quality ones.

Do NOT over volt or over drive! You will let the smoke out.

Asking $220. Price includes paypal and shipping CONUS. Email/PM me here.

Will be posting a DX500 with Fan Kit and a KL-203-P soon.

Thanks
Brad

i don’t expect it to be there in 2-3 more weeks, but if it was, you’d be out of luck.

I don't want to turn into that one guy haha, but I'm torn between this amp or a president Lincoln.... Would like both but just can't at the moment.

SOLD. This was sold on another forum. Thanks for your interest….That’s all folks

 

[NightThumper]

Whelp Mr. Eldorado828 looks like a Lincoln is in your future sir. It’s a great radio

I’m itching to get a second LP-700 monitor so I can simultaneously watch radio and amplifier output instead of switching between the two.
