Why would you want to trash high quality amp. Stock up on 4x800s at $150
each. Have you purchased a Chinese 3-500 lately.

--With the price of the GU-74b's going up and the supply shrinking and is
--almost turning out to become
--yet another 3cx800, i have the following questions

--a) What would be a good tube to replace the 4cx800/GU-74b in an Acom 1000?
--b) Minimal retrofit/gut down work
--c) Assuming the retrofit would be compatible to let Acom put out a new

--I guess selling retrofit kits would ensure
--a) Acom generates some revenue or is a parallel value chain
--b)Builds confidence among its customers
--c)Keeps the resale price of the Acom's stable over time.

"Any thoughts?"
