ORBAN comp + FMR-RNC/RNP

Orban 422a. One channel version of the 424a. Blue face. Works fine but VCA level VU sticks sometimes. GR VU works fine. Can put whatever pigtails on you need. Try it on snare! $300 FMR RNP/RNC with funk logic rack. One RNP knob does not match (original fell off) Otherwise fine. Rack has some "rash" ...

Cool. Mind as well try it out. Does five fish do a 30v? I'm going to do a fixed gain with switchable input pad. Still confused by that other post I linked to though. Thanks

that is what I thought but I found this post: http://forum.allaboutcircuits.com/showthread.php?t=876 and got to thinking about the direction of current flow. Why does this post seem to be contradictory? I guess I could always try it out but the guy in the post wants to do the same thing and is being...

how exactly are the levels screwy? im setting one I just bought up (you can check out my recent post) and had levels coming back from the repro head going weird and there were several things happening. Most had to do with the cards not being seated properly. Also it was really dirty. And im pretty s...

mx5050mkIII global recap? worth it?

I just picked up one of these for real cheap. Im pretty good with tech and trouble shooting and have recapped many things. This deck is from '87 and plays back fine, transport is fine, heads are ok but the record sounds like something is off. Big bump at 100 and kind of harsh top end, a bit distorte...

cool, thanks for the input. I found a compromise of sorts by taking out the 48 supply, putting the power and output xformers 90 from eachother and putting them at opposite ends of the chasis. There is still a hum but it is about the same level as the noise floor. you only notice it when its MEGA cra...

I put input transformers on them. I know this is a general test but if I move the input trans closer to the power trans there is no change in sound. the further the output trans is from the power the quieter it is. Ill double check the power with a scope. im going to move them around today to get th...

its a power one box type transformer. my next step is to move them further apart in the chassis but things are tight in there especially with the stupid +48 supply but that is another story. too bad you need to use a switching circuit to double the voltage. the supply is + and - 24v. got the big dum...

shielding an output transformer from ac hum. .

Hey I have some quad eight cards im racking up and the output tranny is huge and seems to be picking up hum from the power transformer. The level of hum changes as I move the transformers closer together so I am guessing its induced hum into the primary? or something? how have people avoided this in...
