[R-390] The saga cont pt 5

[ka9egw at britewerkz.com]

Just finished paralleling the BFO output coupling cap with a 47pF and the
"Rippel audio mods" [replacing C604 and C605 with .022/600V Orange
Drops--R614 was already 560ohm/2W and measured 556 ohms so I left it alone].

I had to mount the Orange Drops on the opposite side of the board AND offset
about 3/8" to clear the transformer mounting studs and be able to seat the
board properly.  A bit of teflon tubing on the leads took care of the
possibility of shorting.

The difference in audio quality [feeding a 16VCT filament transformer's
primary off the LOCAL OUT and an 8 ohm speaker off half the filament
winding--not ideal but better than it was] is astonishing, even on SSB.  I
haven't added the diodes across R546 and R547 yet, and given how good it
sounds on SSB now, I don't know if I'm going to bother.

Next will likely be C553...but I'm under the weather with this flu and dunno
if I feel like tackling that one today...
