It is true time flies. Back in 2004 I was 17 and had gotten into record vinyl collecting. The going rate for new bands LP's was $10-15. I bought my first turntable, a Pioneer PL-200 for $10 at the goodwill, I still have it and use it regularly. Did anything happen between the early 2000's to...

I only suggested since it caused me some frustration with my unit, and seems the 7070 is susceptible to relay issues from my internet searches. Only 20 bucks and a couple minutes of work, if the order is going in then why not!

You can use 1/2 watt rated metal film resistors in place of the 1/4W if that makes your life easier. I also have a 7070 and went through a similar issue and a random dropping right channel. I have recapped all boards, and replaced every single fuse resistor (which is a must for Sansui of this...

Whoops, yeah that's a typo I'll edit that now. Fuses must have been on my mind haha.

I am nearing completion on recapping my 7070. It has been fun and long process. I went against my original intentions and decided to swap out the power meter bulbs to LED's. I would like to share what I found in detail. The bulbs I used were 5mm "Cool White" pre-wired LED's, with a voltage...

Hey Pete, just going off the pic do you think the leads would be too short to connect with the circuit board? Good find, they're quite a bit smaller diameter but I like the long leads..wait time is long 20+wks :eek: Spacing of the current leads is about 13mm....the hole would fit 10-15mm...

Hello, I'm planning on a recap of my 7070. I've got everything except the large main filter capacitors. Does anyone have suggestions as to a suitable replacement? There seems to be few I can find, and to make things trickier, they are mounted in a weird way. Through the chassis and soldered...

Final update: .............. SOLVED............... I gave the unit to my uncle for a second set of eyes (and a lot more electronics knowledge).... His findings on the P800 power supply board, the Power Supply Voltage had dropped from what I set it (when it was working) 35Vdc to a mere 8Vdc ...

Unfortunately I'm back to square one. The audio cut out again back to highly distorted. I took out the newly replaced transistors and tried another 4 with no luck. I'll be bringing it to my uncles who has a proper scope. I'll report back if we can trace the issue down.

That song was eric b & rakim - what's on your mind Edit: see my final post for the reason this was all happening....

I posted this thread in December but noticed the image server I used basically disappeared...and there is no option to edit. So I will repost for you all... I recently posted a thread asking info on LED replacements. Well long story short I ordered some pre-wired LED's 3mm for the dial pointer...

I hope it is just transistor woes! Just quickly checked the preamp/tone board and no 2SC458's on there, but there are two 458s on the phono P400 board in H405/H406 position. I ordered 10x KSC1845 , and 10x KSA992 for the preamp replacement. If everything works out I will also swap out the 458s...

On the 2250B the pre-amp/tone board are one unit making things a bit easier to work on. Tried the hair dryer but didn't hear any differences. In my searching I just stumbled upon this thread http://audiokarma.org/forums/index.php?threads/marantz-2250-woes.569646/ which describes very similar...

Got it all reassembled but no luck with the shorting inputs. Popped a pig-tail fuse while diagnosing (d'oh) and it cut out all the lights. Got that fixed now. Unfortunately the same symptoms exist; highly distorted crackly sound. When on main-in w/ipod it plays fine, also checked the tape inputs...

Here is a video showing the distortion
