I guess you will need at least 50W for a 15Inch tannoy gold. the challenge is the power ie you will not be able to buy anything since the 110V amplifier is not advisable to be run off 220V even with a step down.
For Class A you can look at 25W +. Why dont you look for Pass labs dealers and go and visit them ? and see if they will get you a 230V
Hi arj,
I disagree with the advice you gave about avoiding a step down.
A step down is
the logical path. It just needs to be done
properly. Use a 2 KVA ( 2,000 Watt ) huge industrial step down. That way, there will be free current delivery on music peaks. 1 KVA I am not so sure of - at all.
This large step-down is actually
far better. You maintain 120 VAC
inside the amplifier's chassis, rather than to have 230 VAC floating around inside, with larger fields below deck.
The
best McIntosh tube amplifier to own for a normal consumer is a pair of their conservatively designed
Mono 60s, with double rectifiers. A pair of McIntosh 30s are just fair, VS the 60s,
but better than their stereo offerings of that era. . All the stereo others in the McIntosh lineup, IMHO, should be avoided,
especially the revered
McIntosh 275 tube amp. It is far too hot rodded.
The McIntosh mono 60s sonically - trash them all. But it is a moot point, they are rare as hen's teeth and quite expensive. The 60s
can be bettered today !!! Monoblocks, BTW, are nice.
A simple beefy
JADIS JA-60 or JA-80
might be OK for 15 inch MGs. A simple circuit to maintain over many years.
Duplex speaker-wise, a new GPA 604 16 inch duplex will today, considerably outperform
all of the vintage era Tannoys. ALTECS also. I know well
the right enclosure - for
that GPA 604 driver.
Guess what arj, my
very first - ever new speaker purchase was in about 1968, fresh out of grad school. A pair of 15 inch Monitor Golds in Tannoy GRF enclosures.
