MRF154s are an expensive way to buy power - basically, they are 4 x MRF150
in a single package - and more than double the price of the single devices -
MRF150s are 30 cents/W.
The thing with a tube amp is that you can collect a bunch of parts from
fleamarkets and build them into a plywood box on your kitchen table to get a
low cost working amp. Not so easy with transistors, but if you compare the
cost of building both using all new parts, the difference is smaller.
