I love restoring these old units. Keeps me busy while on work comp and can be lots of fun. Getting a dirty and not fully working unit then transforming it to a clean, shiny and fully working Boombox is such a rush. I know many of you agree with me and as I said before cleaning up the inside of these old units will help preserve its life span. Dirt is bad for components and holds in heat which will hurt if you keep using them :thumbsup:

So I got this M70 from Aron (Thanks Bro) as partial trade for Restoration on Don's old M90 (M90 restoration post to follow). When I received unit there were deck issues resulting in fast play speed and barely any FF. Upon taking unit apart I found not to bad inside with dirt but there was a broken variable resistor piece. It turned out to be the bias adjustment on the normal tape setting of right channel. The piece was stamped as 100K and luckily I had a spare off one of my parts units so I replaced it and set exactly to left one.

Next I fully cleaned inside unit and blew out all dirt, disassembled deck, cleaned deck including tires, heads and pinch roller, replaced belt, demagnatized head, repaired soft eject mechanism, cleaned speakers nice and painted grills. I also adjust tuner needle and cleaned rest of unit parts.

After completion I tested and set motor speed to proper speed and she purrs like a Kitten. Surprisingly the top slider controls are in excellent shape and work excellent :-)

One post each for antenna hold downs were broken so using JB weld to make new posts, added new deck door label and installed new Blu_fuz strap. All in all I think she turned out great. I didn't take many pics but here is before and after pics. Enjoy pics :drool:

Looks awesome, Bill. :drool:
One of my antenna posts was broken, too. It was split into 3 pieces, so there was really no way of salvaging it, because the pieces were so small. I cut the tube from a Bic pen to length and super-glued it with activator to the case. After 24 hrs., I filled and reinforced it with JB Weld. After another 24 hrs., I drilled out the pilot hole for the screw and re-installed the antenna base. It holds better than the factory posts on the other antenna - go figure. :-D

Thanks :-). My posts were cracked in half so I used JB weld over them but I'm having issues with the weld not hardening properly so I think the hardener is messed up so I just went and got another JB weld kit and will try again with better results hopefully :thumbsup:
