For Sale my KiT88 amp.
Fitted with Sowter U082s transformers and 6550 valves (which I prefer over the KT88s), I built this from a kit a number of years ago. During that time it has been tweaked and upgraded giving a controlled, fast, detailed and un-fatiguing sound. It is a Push Pull Class AB amplifier outputting 28w and running out to -1db @24Khz and -3db @45Khz. I’ve modified the tape input switch so the Tape In input can be used as a power ampler bypassing the internal volume and selector switch.
Tweaks and modifications listed below:
Sowter U082s OPTX - feedback cct tweaked to accommodate the transformers
Matched quad 6550 o/p valves - cathode resistors to 180R for 28W o/p
Input valve 6AUS Jan Philips
Splitter Edicron ECC82
Audio Note Coupling caps
Blackgate bypass caps
Tantalum resistors
Mcaps
schottky diodes
Alps Blue pot wired in pseudo shunt config
Tape/Source switch rewired: Tape = Power Amp in via Tape In RCA’s; Source = Integrated amp inputs
I’ll be sad to see this amp go it has given me great pleasure over the years but I simply need the space! I’m looking for £850.
The Sowters alone would cost the best part of £600 new and if you twist my arm I’ll throw in the original OPTX as well.
I’m happy to demo the amp and would strongly recommend collection from here (South Bucks) as it weighs a ton and isn’t really suited to shipping! Or I’m prepared to travel, within reason, to drop off or meet up.
Regards
Neal
