[Hallicrafters] 6146 again

[Glen Zook]

You are asking for trouble mixing a 6146A with a
6146B.  You can mix the 6146 with a 6146A since the
only difference is in the heater.  But, the 6146B is a
completely different tube from the 6146/6146A/8298 and
usually putting a 6146/6146A in parallel with a 6146B
results in all sorts of parasitic oscillations.

If you haven't read the article on the 6146 family of
tubes that was in Electric Radio a couple of years ago
and reprinted in the Collins Collector's Association
newsletter last month, you can get it on either of the
websites that are referenced at the bottom of this
message.

It does have just 6146's in it but one of my two
ht37's that came ss'ed has one 6146a and one 6146b and
it works ok although I have not had it on the air for
long periods of time. The one ht37 that I have been
using has just plain 6146's.
