Hi - I got the manual for the SL-1100 (which I guess is close enough) from the following site:

http://www.vinylengine.com/

It has a schematic:

So your guess of 18 volts was spot on!

Please take a moment to rate this solution & let us know if the information given was useful to you - Good Luck!

Need a needle for a TECHNIC SL-3350


It's 'TechnicS' and 'stylus'. Wouldn't a web search have been faster?

"TECHNIC SL-3350 stylus"

But even 'technic" and 'needle' would have worked.

Connecting a Technics SL-BD20D turntable to a Yamaha RX-V463 Rece


After further research, I learned that I need to plug the turntable into a preamp before plugging it into my newer receiver. As with cassettes, record players are fading away. I ordered a preamp, but won't be able to experience success until it arrives.

My auto dose not work


Hi! Flipper Do this maybe of help. Turn the power off. Wait about 10 seconds, then power up again. Get close to the reciever and listen for a click-not from the speakers,from the recievers itself.If you hear a click, you can assume that the power supply is ok for that circuit.This does'nt eliminate the power supply problem but it will do for now.You would have to check both the positive and negative voltages from the power supply to see if both are present or if one or both are missing. This would be dc voltages and the positive voltage must be equal to the negative voltage ,if one is higher than the other, the regulator transistors in the power supply maybe defective. The transformer can be checked for AC voltage before the power supply.You know that the secondary is good because the dial lights. For this kind of problems you better change the regulator transistors with desame number.
If i have helped,please click fixya.It is the only way i get paid for my work also,please consider leaving feedback....

My tecnics Amplifier Model # su-v98 has no power. I've checked all cords


Try these test, the only common possibilty would be the transformer and the power supply if both channels are out.You better to check both the positive and negative voltages from the power supply to see if both are present or if one or both are missing.This would be dc voltages of approx.20 to 40 volts.The positive voltage must be equal to the negative voltage,with the exception of their polarity.If one higher than the other, the regulator in power supply is busted already.The transformer can be checked for AC voltage before the power supply.This reciever uses a single power supply so the problem would be,common to both channels.You better change the regulator and checked some capacitor near the regulator.
