Paris Duo - 6EM7 SET Monoblock Amps

After completing a dual mono 6EM7 integrated amp, at the request of an established customer, I built these 6EM7 monoblocks. No built in preamp or attenuated this time. The chassis are 2M thick cast Al, acid etch primed and top coated with epoxy enamel high gloss paint. Only the power tranni, 5Y3 and 6EM7 stand on the top plate. The 10W Edcor OPT and Hammond 5H choke are in the chassis. Gold speaker binding posts and single RCA are on the back. Also inside is a EMI power filter and a short power cord with male IEC power socket and an RF choke connect this Paris Duo to the mains. The PS has a two stage filter: CLCRC/RC which makes this 1.8W absolutely dead quiet. Wire-wrap wire (heavily twisted) connects the RCA to the 6EM7 and OPT to speaker biding post. Silver solder is used in the amp section. Great mid-range.
