Scott,

The 70E-15 is the correct PTO for the R-388.  70E-18 is the 28 volt PTO =
for
the R-392, so they are definitely not interchangeable.  As you say, =
covers
or labels may have been exchanged. =20

The 6JH6 could sub for a 6BA6 in an emergency.  Semi-remote vs remote =
cutoff
pentode.
Perhaps others on the list have tried the 6BZ6/6JH6 as subs. =20

As to front panel, it should be a wrinkle finish.   The ebay picture =
looks
like a flat coat of paint.  Here's your link back, all restored and
repaired:

Have fun with it, post your progress. =20
