Thanks FullRangeMan that Rouge looks interesting. Also an Dynaco ST35 was just listed on USAudiomart https://www.usaudiomart.com/details/650200752-dynaco-st-35-stereo-tube-amplifier-beautiful/ No easy choices in this hobby.

That ad is from Chris Keller in NC.  For years he has been rebuilding vintage amps, mainly Dynacos.  Unfortunately, he has some health issues and has slowed down recently.

4 years ago I bought a rebuilt Dynaco ST-70 from him.  In a word, the whole experience was fantastic!  Amp sounds amazing, dead quiet and reliable, and looks great too.   His prices are more than reasonable.  Chris is a true gentleman with great technical and communication skills.  His 8 pages of stellar feedback says it all:

From there you can also click on the listings and see his beautiful work.   He also did a great job rebuilding my Scott 222B. 

Glow in the Dark Audio reviewed his ST-70:

Chris and his work get my highest recommendation.  If you are fortunate enough to come across one of his products, do not hesitate, buy with confidence!   

PS:    I have no affiliation or association whatsoever with Chris and his business.  Just a satisfied customer.

I'm leaning towards a Dynaco ST35 or ST70.

I started out with an ST70. Had ST35 on loan too. Ultimately I liked the ST70 more, especially in bass authority. Downside now is 7199 front-end tubes no longer made and originals getting pricey. For what it is it's a great tube but now would want an ST70 with a modified front-end using commonly available tubes. There are a boatload of front-end options now. Recently picked up another ST70 (At a yard sale!) but not dug into the current faves.

All that said... the Lintons are 90dB efficient. Depending on your music & listening tastes most tube amps OK there as 90dB highish. There is an issue with using the ST35 however. It has 8 & 16-ohm connections only whereas the ST70 has 4, 8 & 16. Linton's listed as 6-ohm nominal, 3.5-ohm minimum. You'd put them on a 4-ohm connection which eliminates the ST35. You could use it but bass will suffer and likely sound "flabby". Whether you decide on an ST70 or something else, make sure it is 4-ohm compatible.
