Hi All,
I'm new to this list so forgive me if I've missed the appropriate thread.
Recently I purchased an Alpha 76A (3-holer) without tubes. My intent was to
convert it to a pair of 3C(P)X800A7 tubes, but so far I haven't been able to
find them at anything less than breathtaking prices if at all. While
pondering alternatives I ran across numerous 3C(P)X1500A7s for sale in the
$200-$300 range.
Does anyone have any experience with or advice on converting this amp to one
3C(P)X1500A7? I realize it would require a socket replacement, but
shouldn't require an additional filament transformer. It seems that a .1
ohm or so resistor in the filament line should drop the voltage down to the
required 5 volts. Does this seem doable or am I way off base here?
73s & Happy New Year,
Chuck
