had supposedly just returned from the tech after a good cleaning....mmmm hmmm...

there was popping in the audio when cycling the toggles but it would go away...then come back. symptoms of leaky caps allowing dc on the switches.

jvc does not like removeable bottoms.

the main filter caps are within tolerance so they stay for now. i have caps that could have been fit and a jumper made but no need atm. i got a nice pair of vishay 3 legged caps in my mouser cart that should drop in.

they use a glue that gets super crusty and when removed, it leaves the board stained but any jvc gear that i've had on the bench has not had corroded leads from the glue.

that lone cap on the fuse board, next to the resistor is a .47uf polarized electrolytic...the schematic calls for .12uf film. the pcb has a non polarized symbol for a film cap.

i got a feeling that they installed that polar cap for a reason so that's what i replaced it with.

power supply is done. line amp is done.

relay board is done

problem is gone.

i'm in no hurry to recap the filter board. it's going to be a pita so until the day comes that i need to disassemble dirty sliders or something fails, it's staying original.

JVC shipped with lots of cuts and jumpers on early Rev boards ?

Going to Bed listening to Dido My Jays with a possible chance of a wild card fall to the Tigers my childhood team and a long shot of the wild card
Be sure to take it easy for a few weeks
give your body a chance to heal any un detected damage
Repair and immune system turn on when sleeping, 1.5-2hrs in the middle of the day is good.
Stress kills, anything or anyone that stresses you turn them off for a few weeks.

Olive oil is almost identical to the fat each cell stores for emergency food, it absorbs directly into every cell
Zinc is the immune system, when cells can't absorb more they cover themselves with it.
- zinc dissolves -breaks the bonds between DNA strands of invading viruses
Tonic water with quinine opens the cell walls to absorb zinc, good for us old timers but only if taken together.
- I usually add bit of lemon juice, or slice of lime if on hand.
- My good friend, RIP, took 1 with gin every night after dinner.

Glad to hear you are OK
