    Technics SU-G91

    I've got this amp playing in my garage and all the issues, except the remote, are things I deal w/ as well. I need to replace the fan for sure - it's hot and the fan barely turns - just noticed. The dry sockets are a nuisance. I have the equalizer SH-8018 as well but none of the others. Found...

    Epi 100v

    Found a pair of these epi 100m w a $11.00 price tag. the cabinets are in great shape I couldn't get the covers off to look at the speakers I think I'm going to go back and get them and do the upgrade. make sure you get some desoldering braid that makes the job really easy and you'll find that...

    Microwave Oven Problem

    I'd give the repair a shot. I replaced the Magnetron and found the repair to be quite simple. The voltage regulator needs replacing soon but it can wait for now. Parts cost were cheaper than a new one.

    Part ID

    This is a Proscan TV issue. It's just for fun to see if repair is possible. As I attempted to remove this part( Green disk w/ one leg) it pulled apart. Now I've desoldered and put in it's place a varistor thinking that was an equivalent. It didn't behave - no red light on front panel -when I put...

    How can the USB cable be improved?

    Not really other than to say that the mini usb and the hdmi guys got it right.

    Magazine stuck

    I just picked this Pioneer CDP (PD-Z85M) up for $3 as a favor to my bro-in-law and I can't get the cartridge out :no: If it fails to play, no big deal. I need another 6 disc mag. but I can't get it out!! I removed the front panel to get a grip on it but it's in there to stay. Releasing the...

    How can the USB cable be improved?

    Not sure if this will help your particular desire but the reason alot of xbox game consoles fail is because the attempt (but kids mostly) to connect the cable to the console (male to female) causes the female to breakdown, shorting out the console. If this issue is addressed you'd improve the...

    SA WM-200 Subwoofer salvage effort

    Leads resistance is 0.7 - kinda high I'd guess. The Dual emitter is 5W (2- 0.22ohms) then 202 printed below. I'll post pic. When I measure from leads out of circuit outside to opposite outside it reads 1.2 ohms. So I broke out my other DMM (better quality w/ .1 resistance between leads) it...

    SA WM-200 Subwoofer salvage effort

    Check R401/R402, both should read ~680 ohms out of circuit. R403/R404, both should read ~10 ohms out of circuit. Do a diode check on D401, D402, D403, and D501. D401 is a full-wave bridge, so there are really 4 diodes in that case, you will need to test all 4. R308 should be a .22 ohm...

    SA WM-200 Subwoofer salvage effort

    Those are the pins from R308 the dual emitter resistor w/ the three pins sticking out of the top. Everything is out of circuit. I'm assuming the IC failed and hence have replaced it. It's in place. Check from pin one to 6 is opposite side opposite end. The Mouser part is 1/5 the price of the...

    SA WM-200 Subwoofer salvage effort

    I got back around to checking the resistors today and this is what I found: R401/402 are OK - 666 Ohms R403/404 are OK - 10.5 oHms R314 is OK - 1.5 oHms But R308 - the dual emitter resistor - I'm not so sure about - I should mention that the was a slight discoloration in the ceramic...

    SA WM-200 Subwoofer salvage effort

    JW401 & JW402 are not there JW403 & 404 are in place. I haven't had a chance to pull anything off yet. I'd really hate to pull that IC that I just put into place....removing a few other things - no big deal, but I'd like to avoid that IC if at all possible. I bypassed the DBT with the main...

    No worries there Westend - I appreciate your input. The DBT is still in the loop @ 100W. So the AC voltage seems right from the tranny output?

    AC between 3-1 pins 36.5 volts - 3-4 pins 36.5 volts AC between 6-5 pins 22 same between 6-7 pins, 22 volts. D401 dc measured 17.9 volts between the end (+) and the other end -. There is no audible click and all boards and the speaker are in place at the moment. Thanks

    SA WM-200 Subwoofer salvage effort

    Thanks guys - I unplugged the 7 pin from the Main board and measured AC for the two outer pins - 7 Measures - 16.5, 1 = 2.4. There are symbols on the rectifier - + ~~(-) the two end pins measured 8.6 v DC +/-. Make sense?

    SA WM-200 Subwoofer salvage effort

    I put it down for a few days...my question is how to ID the rectifier. The manual makes no reference to it. Westend made reference to it....but I need more info. Q401?

    SA WM-200 Subwoofer salvage effort

    I'm about to that point - Just plug it in and see what happens......now when I power up w/ 100W bulb in line it pulses bright. Having replaced the caps and the output IC I'm about maxed for what it's worth.

    Transformer swap After checking for proper voltage it appears the tranny is a question mark....I found this in a Technics AV receiver. Could it work?
