 Ameritron ALS 1306 Like New $2000  
For your consideration, an Ameritron ALS 1306 1200 Watt SSB 160-6m Automatic Band switching Amplifier. This Ampifier was sent into Ameritron for inspection, MOSFET replacement and full testing to be operating like new in late 2023. The amplifier has been stored, unused since it was sent back to me.
It’s like buying a freshly restored amp from Ameritron, because that’s exactly what it is.
I don’t have use for an amplifier anymore.
This amplifier is beautiful. Waiting for a new owner to enjoy its great operation. $2000 plus buyer paid shipping.
Zelle preferred but also PayPal and major bank cashiers checks accepted. Once the money clears for the amp and shipping, I’ll send it right away to your destination. Im a very strong seller with a great reputation for great communication throughout the sale.
It’s time for it to find a new home. You’ll love it.
