 Alpha 91b  
In great shape! 1500 watts plus out with only 38-40 watts drive depending on band. Has the very affordable 4cx800 tubes which are still available new at DX Engineering for under $700 a pair in case you’ll need new ones in the future. But the tubes in this amp should last a very long time so long as amp is not abused.
$2000.00 firm local pu only please.
All sales final, no return/warranty.
Text me if interested. 586-864-4563
Please check my feedback here on QTH and QRZ then buy with confidence.
Thanks.
