Hello-
    I apologize if I am taking up too much time here. I wanted to ask for 
advice
on selecting a set of 811A tubes for my 30L-1 amplifier. I know that one 
option
is to scout around for a set of RCA types. The last time I had a 30L-1 about 
12
years back or so I recall buying a nice set of Svetlana ceramic based 811A's
that were highly recommended, but they were for spares, and I never had to
change out the set of RCA's that were in it.
                                                            Thank you,
                                                                        Byron
