Gad, I can't believe I wasted my beloved Meridian 203 on a valvehead!
Not even a decent amp either, just a Mullard 5-20 clone! :-)

Hey! That's a hand-made classic! :-)


....and I'm in the process of building something very similar - mostly out
of even more inferior bits! The OPTs seem to be guitar amp ones without UL
taps and I think the mains trannies are probably too small (I don't know
the ratings - they came from a radio rally - but at least they are the
same!). I'm not expecting wonderful results - and I probably won't get
them. :-( The price is ok though. :-) If it costs a lot you're doing it
wrong...

Ignore him Wally, he's sold his soul to the Devil for a DSP-Z9 ...

Is that a motorcycle?

Sounds like a Z-systems processor to me - I should be so lucky!

Everybody knows that valves are better 'cos the electrons don't become fully
mobile until they're heated up - the resulting agility in the
cathode-to-anode transitions gives an improved the slew rate...

Well, there *might* be some truth in that, but unfortunately those
electrons have to travel several millimetres from Anode to cathode,
which is a thousand times longer than the distance they have to travel
across a semiconductor junction. That's one of the reasons why SS
audio amps usually have a higher slew rate in the real world........
