David Berning designed power amplifierFern and Roby case,
Factory KT77 tubes
Very little use
Amp is 3 yrs old but I had the Fern Roby chassis upgraded about a year ago. It's a perfectly operating/sounding LTA ZOTL40 MkII in near mint condition.
Minor flaw to matte finish paint on top of case, otherwise in perfect condition- see pictures
