[Heathkit] tubes in the HW101

[Tom NØJMY]

Hi, Dick.  Ken Gordon W7EKB will concur with you.  He uses 6AH6's in 
place of 6HS6's in at least one of his SB-line transceivers and he's 
quite enthused.  I believe, Gm spec's notwithstanding, that there is 
very little noticeable difference between the two except the price.

It is also reputed to be a more stable replacement for 6AU6's in VFO 
applications such as in the VF-1.  Even more so if the B+ is dropped 
down to +108V.

73,
Tom NØJMY.  .
