This listing is for a Pair of Schulmerich Mono 6550/KT88 Tube Amplifiers Models 6-228G & 6-228H EXC Sound The amplifiers are in good working condition and sound excellent. They had a very well qualified technician look at them and  had a couple of filter caps replaced. They sound great and are of the better sounding amps of that era that I have listened to. The amplifiers sound similar to Allen Type 75 amps, Grommes 260A amps and are quite musical in my opinion. The amps were made by Schulmerich for their Carillons.

The Tube complement of the amplifiers are a pair of 6550 (or KT88 could be used) output tubes a pair of 12AU7 tubes and one 12AX7 tube. 

The cosmetic condition of the amps is described in the many pictures that I have taken of the amps.

Due to age the items are being sold AS IS.


Disclaimer: When buying almost 50 and 50 plus year old electronic equipment that has not had all parts replaced with new parts there is always the possibility with failure to the 50 year old part/s at any time. Some of the electronic part/s may continue for another 50 years without need of replacement and some electronic part/s may fail a few days after you start using the item. The item will arrive to you in the working condition as described in the listing but I am not responsible for what might happen to the electronics part/s after the item is received in working order due to the age of the electronic part/s.
