Klemt Echolette M40 4 Channel Tube Amp 1960s/1970s Gold

Rare Klemt Echolette 4 channel amp, listed in catalog as a P.A. head, but like the Marshall P.A. amps, it's a MUCH better guitar amp ! I bought it about 10 years ago, had it serviced, and put it in storage at a studio I work at occasionally.  They're downsizing now and need the extra space. The amp features (4) EL 84 power  tubes, and (7) additional preamp tubes ( all Telefunken ). (3) speaker jacks (6 or 15 ohms). Selectable AC power for use in most countries without an outboard transformer (2 ) din-type jacks for tape and output. (4) 1/4" input jacks with individual volume controls, master volume , treble and bass controls. Solid construction , very heavy ! Works as it should. Sounds like a Vox AC 30 ! Loud !!  I think a foot switch could be made to select different inputs at various volume levels to increase versatility.
