Collins 204F-1 very good working Cond: Price Reduced Collins 204F-1 is in very good condition. This is the last time I will list it here. I will try eBay, Then I will scrap it for parts. It is working and was on the Air. This Amplifier uses a pair of 4CX1000 tubes and will run 2.5KW 24/7. It was run using a Bird 30DB attenuator at 100 watts, Included. Dusty on the outside. I have extra pics for serious inquiries. This is best if picked up in Northwest Oklahoma. If you want it shipped the buyer would need to arrange packing, shipping, and pickup. I'm selling it for 3000.00.
I accept, cash, PayPal FF, and Zelle. All funds would need to clear my bank before the item is released.Thank you. 469 628-2221; Listing #1649875 - Submitted on 08/04/23 by Callsign K5YHX, Modified on 09/27/23 - IP: 207.235.149.131; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
