There is no reason one could not take a pair of the surplus GI7B, remove the
finned radiators (nut and a couple of washers), and attach a big finned 
heatsink
like the SB230 had. The anodes are grounded and the heaters are run off 
a well
isolated transformer. Drive is transformer coupled as well. It will cost 
a little
more than doing things the 'conventional' way, but for no fan, it's 
probably worth
the trouble.
