    HH Scott LK-72B

    I recently received a Scott LK-72B from the usual place. It is very clean and all original except for the tubes. Both 6U8's were bad, one shorted and two of the 7591's were extremely weak. I put in two NOS RCA 6U8's and s decent pair of 7591's and brought it up on the variac. It powered up ok...

    C2200 Balance Control has become Input Selector!

    Hello all -- I turned on my system this morning and noticed R channel output is lower than L channel output on the meters of both preamp and amp. When I push the mono switch both channels sound and look to be on the meters at the same level. Now here is the strange part. When I tried to...

    Denon PMA-860 input selector and balance control are not working

    Hi all Got this Denon PMA-860 recently. It has a problem with the input selector switch and balance control. To select a source you need to rotate a knob few clicks past a desired selection in either direction. This makes the last ones on the right and on the left unelectable. Left channel has a...

    Toshiba SA300 Balance issues

    Hello everyone. Just signed up after months of spying the threads as my interest began growing in vintage receivers. I got some really good information from those threads. And so finally I myself came up with an issue. I got my hands on a Toshiba SA 300 (practically free) and after cleaning the...

    Harman Kardon PM650 Broken/Dodgy Balance Control

    The Balance on my Harman Kardon PM650 doesn't work. Mono works through both speakers. Stereo only works through Left channel. Reverse setting on the dial works but swaps it to the Right Channel, with Left (which should be swapped to Right, still not working. No sound.) Stereo doesn't...

    Balance Control Pot solution?

    Restoring vintage HiFi amps usually involves replacing the Balance Pot? Unfortunately, these centre-detent pots that provide zero resistance in the centre position are virtually unobtainable. I had an idea... how about using a many-way, make-before-break, 2-pole switch instead? A suitable array...

    Left channel sounds louder than right one - DENON DRA-635R

    Hi all, I just noticed that my DENON DRA-635R amp channels are out of balance. Left channel sounds louder than right one. In headphones the sound seems to be balanced, when Speaker on/off is in off position. However, when the speakers are on, even in the headphones left channel sounds louder...

    Balance Knobs- who actually use it?

    My stereo receiver has a balance knob. That one has a balance slider. That one has a dial. Do I use them? No. Yes. Sometimes I use 'balance' control to test each side for sound. Then it goes back to the middle position for the remainder of its life without use. It's not like today I'll just...

    Pioneer SX-D7000

    New to the forum. I've got a Pioneer SX-D7000. The volume/balance control knob seems to be touchy, as the right channel sometimes goes in and out. Tapping on it lightly typically brings it back, or simply adjusting the volume a little bit. Any suggestions for what the fix might be? Thanks ahead...
