Herron VTSP-1a/166 - basically new! [Expired]


no longer for sale

For sale is a mint condition Herron VTSP-1a/166. Though discontinued, this actual unit was built in 2014 and this can be be confirmed by Keith Herron. Not a mark or scratch or anything else for that matter, absolutely perfect. Factory box included, of course. Brand new matched set of low noise, platinum level NOS Matsushita/National PCC88 tubes from Upscale installed on 10/3. Verrrrrrry smooth so far. The reviews on this piece speak for themselves. Please contact me with any questions you might have, open to possible trades, etc. Thanks and please check out my other ads.
