Thanks to Jim, Larry et. al. for the great advice on my Valiant
restoration project.
I'm very interested in the common wisdom re: the 6146 variants that
'work' in this rig.
Now, I've been a boatanchor fan since they were state of the art - have
done quite a bit of tube design, mostly audio though, and I do have quite
extensive documentation on most tubes made in the last 100 years.
So really there's probably no excuse for this question other than
laziness - what exactly are the 6146 characteristics that the Valiant
design "favors" over the other variants? A freind who has re-built a lot
of these rigs says to only use 'plain' ones. In my ignorance, I bought a
nice full set of 'W's and the transmitter wouldn't even resonate on
any band. ;{} I put three 'B' s in the finals, and we're where we are now
- OK on 20M and above, 'runs away' below that.
What do y'all recommend for Valiant finals / modulator tubes?
On the HV B+ filter issue - mine are iffy, were replaced sometime in
it's history, but I'm going to renew them - what is the recomendation for
a more 'modern' replacement - keeping in mind that I'm looking for the
best AM fidelity I can squeeze out of this rig.
Cheers
