I am looking at my first tube amp. It delivers 40 wpc
class A. I own an inefficient pair of A/D/S 810 speakers.
Will I have problems with this amp driving these speakers ?

The ADS L810 is a three-way acoustic-suspension
speaker (1981). This is an efficient 6 ohm speaker
(94 dB SPL/W/m) with a power rating of 100 watts,
200 watt peak. 40 watts of tube power should be
sufficient for a normal sized room unless you play
your music at excessively loud levels.

Perhaps if the room is small or very live.

If the L810s have 94 dB/w sensitivity, they would be exceptional as most
ADS products run in the more typical 88 to 91 dB/w range.
