TUBES - 3CX1200A7 Up for sale is a used 3CX1200A7. This 3CX1200A7 has had a hard life but it still mostly works. Do you have an AL-1200 or a homebrew amp needing this tube? It is for sale - $1000 shipped anywhere in the USA. Tested to be at 75% of capacity by Richarson Electronics. A copy of the report is available. $1000 includes shipping. Insurance is not included. Cashier check or cash on pickup. On 7.070 Mhz (CW at 100 watts in) into a 50 ohm dummy load in my Henry 3K I get 1500 watts. When I pulled it out of my AL-1200 I got 1000 watts out. I suspect this is due to the higher plate voltage in the Henry 3K. People who are local are welcome to come over and check the tube before pickup. As is sale with no warranty for used 3CX1200A7.
