Default Hartung / Prestla OTL amps


I came across the Hartung Stereo OTL on ebay, has anybody bought one? or their Prestla monoblock equivalent/s? If so how are they?

Hartung OTL

Both are available in kit form etc.

First, I have never heard one of their amps, but just from seeing the pictures I wouldn't buy one.
The space between the tubes is too low, furthermore there aren't any vent holes in the chassis. One 6S33S produces about 40W only with the filament ! A good chassis concept and vent holes are necessary in my opinion.

Thanks. Yes, they are very new, I imagine it will take a while to develop a name for themselves of course. However, I have put your observations to them.
