[QUOTE="Mars, post: 97580, member: 817"] Hi All I'm sorry I have missed the interesting thread up to now. I had a look at the brief * At least 100W (continuous) per channel into 8 ohms - should almost double into 4 ohms * High damping factor (>500) * Low THD (<0.05%) * Fairly efficient (class A/AB) and physically not too big I would recommend aiming for 50+50 watts when talking about tube amps in the R12K bracket. 100watts of tube power (at 1%THD) should satisfy most home requirements. THD climbs fast after 50watts, and the price even faster :'( You can see a example of a Ultra Linear 50+50 that I do here. Consider if the size fits your fancy. The width is 420mm.

The preamp tubes will be 6SN7 in the front. [/QUOTE]
