No, not that I know of.  Dallas, and then I think they are planning on going to Seattle again in early Sept.  You should write them to see if they are planning on going to the east somewhere.  You can contact them via their site.

Just a note that Spatial will be at the SW Audio Fest in Dallas, March 15-17.  They will have the final production versions of the Raven preamp and Blackbird mono 300b amps driving their speakers.   I will be there all day Friday and Saturday, and...

Well, they are really fast:)

@downtheline Actually, next up is a two stage amp with another lovely DHT in push pull for a whopping 3-4 watts at very low distortion.  Not a 300b so not for this thread!  You could hang a custom transformer off it for phones.  You would want a R...

@downtheline  The Raven has a headphone jack, yes, but as Lynn noted, it will only drive the typical old style phones.  It will not drive planars.  Sounds great with my old Sennheisers and phones of that type with 300 ohm impedance.

... Actually, sonically the statements and the Blackbirds have similar heritage, but the Blackbirds are much better.   The Monolith Magnetics iron is just sublime, plus the power supply is improved in several ways including the addition of the pai... 
Linlai KT88 experience?
The Linlai WE 300b exact western electric copy is in my amps.  We used them at the Pacific Audio Fest.  They are wonderful and I stopped looking at 300b options when I got them.  There may be better 300b tubes out there, but I really don't need to...

@tmhaudio Sorry, but I will not wade into the Linlai global vs ones you can buy elsewhere.  Everyone has an opinion and I have mine........  
Linlai KT88 experience?
I now have about 50+ hours on the Linlai KT88-D.  They are stable, no issues, and the sound is stunning.  Again, these are drivers in the 300b amps running about 15 watts, and not used as output tubes.  That said, they appear very well made and I ...

The gear could easily be wired for 220-240 VAC 50Hz.  Everything we use supports it except for ordering multiple primaries on the power transformers.  Again, the project must get off the ground in the USA/Canada.  If they are selling, and people f...

I have a thorough dislike of working with lead-free solder.  Nothing flows in a point to point build like a good 2% silver solder.  Lately I have been using Wonder Solder for the past year or two and it is just wonderful to work with.  Of course, ...

@tmhaudio  I heard some Sophia blue glass when I was doing the vintage work and a fellow sent me a quad to use with his citation II amp that I was restoring.  Sounded good, but I only listened for an evening and the amp had all new caps and power... 
Linlai KT88 experience?
OK 25-30 hours.  As expected with any good KT88, they have really opened up.  The other KT88 I have run as drivers in this amp is the now unobtanium Shuguang WEKT88, which was their best KT88 right before the factory shut down.  The Shuguang WE se...

@pindac Would it require a 240 VAC version or have most of the ones you have heard been US market 120VAC ones that someone was using a step up transformer with on your side of the pond?   I will say that I have the pair of prototype amps that will... 
300b lovers
@pindac that will be up to Spatial Audio Lab.  I am going there in late Nov to teach them the builds of amps and matching preamp.  There will be a review pair made that will spend some time in the USA next year.  After that we shall see.   It is n...
