The gu78b tube in the om3501a or in 3501 is again produced, the latest I saw on the market was 2016, affordable. The anode cooler surface is greater than the gu84b, less air obstruction also. The output is by specs 2,5kW 24/24 7/7, It will handle the 3,5 kW output in ICAS, all within the specs as anode voltage/current/sreen and grid current.
