 Alpha 9500   
I have a Alpha 9500 amplifier for sale which was gone over by Dishtronix and new Hall Effect Sensors installed in lieu of the original pots. It was picked up at Alpha/Dishtronix the week of Sept 16th 2024 and only used to create a video. The video is lengthy, but is in my Onedrive account. I can share the video upon request.
It shows it working on ALL bands in the RF Sense mode.
It is in Excellent shape as can be seen by photo's. A couple minor scratches on the top cover. You will receive the original manual, original deck box and original transformer box. Price is $4000 shipped to CONUS, OR it can be picked up in Waterford, MI at a discount.
Payment method is PayPal (Not Friends & Family), or Cash. No exceptions.
By the way it was not cheap getting Hall Effects installed and the amp gone over. Hence being priced over others I have seen. This amp got me the DXCC Challenge award of 3009 confirmed, and it can you too.
More photo's on QRZ.
