Hi all
I have just bought a trk-3d88 and having some problems with the sound. Sound seems to be ok when i select radio and dubbing on the select switch when i move switch to tape and cd line in the sound is very quiet. Now if i move the switch half way between radio and cd line in i start to get some good sound coming from the cd line in. Im i right in saying it looks like the select switch might be the problem, i have seen other posts saying about cleaning the switch would this help, if so how do i go about cleaning it. I have taking the unit apart and located the select switch how do i clean, do i have to take the whole switch of the circuit board to get to the switch or is there an easy option and what do i clean it with would really like some help hope someone can thankyou.

sounds like you just need to clean the switch , this can be done easily, no need to take it off the PCB, easy to locate to, can use any switch cleaner as long as it has a lube in it to, while you have the box apart may as well cean the record/play back switch, hope this helps

a lot of people swear by the brand deoxit, just a couple of small squirts and work the switch, its really simple, cant really do anything wrong

Thanks for your help T-STER i have order some of that stuff up and will give it a go at the weekend.I'm reliving my childhood playing with my TRK-3D88 I originally had a TRK-3D80 as a kid,there's a little bit of different between the two models but not a great deal.Just in the middle of stripping the whole thing down and giving it a good old clean now
