Same is true of Roger Modjeski's creations especially the RM-9 and RM-10 amps. I owned the RM-10 and it is a little powerhouse EL-84 beautifully built.

The opposite is true, it seems of Jolida. Many listed, few sold. My 202A has a better soundstage than most of it's type but a problematic treble. As 'Carl the greenskeeper' would say,"It's a little harsh". Also there is a lot of flux residue on the solder joints. Older production, I'm sure as most of what currently comes from China is first-rate in build.

I just ordere some inexpensive Obbligato aluminum foil caps from DIYHIFISupply to replace the metallised polyprops used as coupling and signal caps. Maybe that'll tame the treble.
I love EL-34's!
