[Heathkit] re 8873's, etc

[Fern Rivard]

`They also used that 8873 tube (actually a pair of them) in the Henry 2K 
Ultra which was a very compact desk top hf amplifier. I have one of 
those which is surplus to my needs with a pair of 8873's if anyone on 
here is interested.  I also have an NOS pair of 8873's that the 
purchaser of this amp would have first option otherwise they will be 
sold afterwards. A pair of these with about 60 watts of drive or so, 
puts out an easy kilowatt dc key down.
    Cheers from Fern
