Hi there,

I just received a Knight KA-55 integrated stereo amplifier (40w)from my friend. He purchased from an estate.

However, there are only 4 pcs. of RCA 6973 tubes included in this amplifier, all other tubes are missing.

I can't find the schematic of this amplifier from the website. Does any member got the schematic?

Thanks for your help.

Knight schematics are among the HARDEST to find - but fortunately, this one is covered in Sams 1139-SED. It will be a schematic only, not the usual folder with parts list and photos. You may be able to get it from Walt at infotronix.us or Bob at findatube.com.

You are also lucky that the 6973s are present... they run about $35-50 each for NOS - EH has new production but I don't know how good they are.
