Here are some images of the 300 watt amps.....
Tube amps can look dramatic at night because of the blue glow
It isn't dangerous to be near tubes that are on; its just a
occurs when tubes are healthy.
Another night pic....
This is not a trick picture; there really are a dozen 6550 to do
A daytime pic of the amps.....
The connection of the speaker cables is now not as shown but
the output transformer ends of the amp chassis.
The 12 red leds near the middle of the amp chassis ( just
to indicate if the bias for a tube is wrong.
The latest amp version has now just 12 x 5mm dia holes with 12
test points so an owner can easily measure the cathode bias
tube in 2 minutes to see if all is well perhaps every 3 mths.
Active protection will protect against any serious problems.
Umbilical cables between the power supply and amp chassis are
crane cables meant for 415V 3 phase mains supply with 5 inner
each black insulation sheath, each one rated for 20 amps.
This picture taken before about 2002 is entirely historical, and
the same dude
in 2014 looks older, and he confirms the fact that the
older a man gets,
the better he was. He's not making as many amps as he was, but
occupied by soldering on towards old age.......
