[Heathkit] Re: need mod info for SB-100

[Ken Kaplan]

Shouldn't need it. The HW-101 already uses a 6HS6 in the same circuit as the SB-
102. It even uses the 6HS6 for the first mixer. The HW-101 is speced at 0.35 
microvolts like the SB-102. For some reason (cost?) Heath went to the 6AU6 in the 
SB-100 & SB-101. It looks like 6HS6's are getting scarce (and costly). btw - there are 
lots of HW-101 mods documented and service bulletin info on my website.
