Hello Gents,
I recently received a 100 watt 6 meter amp. A very kind gent gave it to me and 
it works. But he had no documentation for it. It was a kit he got some 30 years 
ago from another ham in Japan.
He told me that it was IIRC Toko.I remove the cover and printed on the PC board 
in trace printing, it said RADIO HOUSE R570.
It uses a 2SC2097 final transistor.It also has a receive preamp in it.
By any chance does anyone have any further info on this unit? A schematic would 
be great!I did a pretty good search on line but came up with nothing helpful.I 
just like to have schematics/info on equipment.
Any help would be great.
Thanks so much!
