Luxman LX33 Integrated Tube Amp. YEAH? NAY?

Perhaps the Russian Tube Preamp disaster will lead to this different solution:  All Tubes in one shot.

Luxman Vintage LX33 Integrated Tube Amp for: Small Office system:  TT (MM); R2R Tape (line); Computer (line).

YEAH? NAY?

30 wpc Enough Power? I think so. I would go Luxman pre-out to self-powered sub's line-in first, then sub line-out to LX33 Main In: so the LX33 and Wharfdale 225's (low 87 sensitivity) would not need to produce low bass.

This LX33 and other Luxman's are Shallow Depth. They fit on top of my 3 shelf high bookcase, next to my Vertical TT and Vertical R2R deck (nicest no-bend operational height I ever had). 

 The Fisher Mono Blocks are also 30 wpc. (35 wpc if I want to get EL37's, no thanks, I'd rather eat).

Not the wood look like the Russian preamp or even nicer Luxman Preamp 35iii,

but the LX33 Brushed Metal finish next to the Grey Mistubishi LT-5V are compatible.

Elliott

A new find: Luxman Tube Integrated (MM, MC, remote volume)

https://www.canuckaudiomart.com/details/649730439-luxman-sq-150-integrated-tube-amplifier-w-mcmm-pho...

only 10 wpc for 87 sensitivity speakers? IF sub takes the bass?

from Raven’s formula 10 wpc with sub is like 30 wpc. I sit 6 feet away, don't need loud.

"High-Pass Crossover

The Avian MK3 series high-pass feature provides an extraordinary advantage when using a subwoofer. By removing bass frequencies, it frees the power amp from 65% of the load it normally has to bear. This is like tripling the power of the amplifier in terms of its ability to drive speakers. It also frees smaller speakers from reproducing low bass frequencies which reduces speaker distortion. This is all achieved with a gentle 6db per octave slope making it easy to achieve a seamless and musical transition with any good quality subwoofer."

Elliot the SQ-150 is an excellent little amp a friend has one and loves it. But even with your sub handling most of the bass duties I still think 10 watts would be a stretch unless you have a small room and/or listen at low volumes.

The Luxman CL-35 III is a good preamp, but ...

I would only buy one that was constructed to run on the voltage where I lived, and this one was designed to run on 100V AC in Japan. I don't know where you are located, so this may or may not fit qualifications I would desire.

@jond  +1 on the SQ-150. Sounds great, but needs efficient speakers

You are right, 10 wpc is borderline. I'll probably go for more power just to be safe. If I risk it, and too small, what else would I do with it?

check out this compact beauty from the 60's

20 wpc, now were talking!

Thanks for commenting. I'm USA 120v.

I use a small 120 to 100 transformer for my 100v JVC TT81 Turntable, zero hum. My concern is I move stuff and forget it's needed and plug directly to 120v by error. I think I'll put a wire tie on the plug/transformer to prevent that.

IF the transformer is noise free, is it more of a concern for an amp? I suspect it's done all the time.
