Glad we could help, including your peace of mind(re: gain controls). HAPPY LISTENING(to both of you)!

No- those would be gain/input level controls, without which you will get full input level(no attenuation), assuming the pots were simply bypassed. You should find wiring, from the input RCAs to the circuit board. One connection close to a 2.2uF cap and another to a ground point(which may also be on the circuit board, or the Stereo/Mono switch), for both the L & R inputs, of course. If I had a professional amp, that I intended to use for home audio, bypassing those would be my first tweak. See page 8, for info on the gain controls: http://www.hafler.com/pdf/archive/9130_amp_man.pdf |
Remove the top plate and you’ll find the switch’s wiring has double-crimp disconnects. Possibly- a capacitor(.01uF), across two of the terminals, to minimize turn-on transients. Before removal, annotate the wiring and switch orientation(ie: LED on the bottom of the rocker). Once you remove the wires, you’ll find expanding retainers on the switch body. Compress those, and the switch should easily push out, through the front plate. Reverse that order, to reassemble. |
