350 W/block, wow! What tubes are in these?

6LQ6 horizontal output tubes. This tube was also popular with CBers who used them in illegal linear amplifiers.

Anyone who can see a McIntosh demonstration at a nearby hifi shop should make the trip. Forget about the sound, the whole visual experience is breathtaking! Love all the black lacquer and the lighting schemes.

My uncle basically gave away his MC2105 once he 'got into tubes'.
