SOURCE: technics sl 1210 will not start up

did you ever open the turntable. It sounds like the on/off switch is bad. Remove the platter and screws with a phillips screw driver and just make sure the connections are in place. make sure you disconnect the power first. let me know what happens afterwards.

Technics Preamps on eBay:

There are, of course, many non-Technics PHONO preamps out there.

If you already have the central receiver and amplification part nailed down you really only need a Phono Preamp to boost and shape the output of the Phono Cartridge. Otherwise you're paying for source switching, volume and tones controls you don't need.

SOURCE: When I turn on my Technics 1200 MK2 the 33 button

33 1/3 and 45 RPM Selector;---With these selector you have to choose the playing speed of the platter. Most 12" vinyl records with 1 track need 45 RPM, all others 33 1/3. Although this is no hard rule you could use it as a general guideline.----------
Pitch bend trick when on 33 1/3 RPM:---Some people use a little pitch-bending trick when the 33 1/3 RPM mode is selected. When a track is playing you can hold down the 33 1/3 RPM button and at the same time press the 45 RPM button. The speed will increase to 45 RPM but when you use it with tiny little pushes you can perform an un hearable positive pitch-bend.
------------------------Its quite possible that this buttons are getting jammed, they are not making proper contact.Try spraying contact cleaner spray directly to the side of the button and let it remain there, then press both 33 and 45 buttons few times and see if that makes any difference, but if that is not helping then,it sounds like a short on the pcb, one of the IC's could have gone bad, or the 33/45 have shorted out. -------- So its working on both 33 and 45 speed but not switching from 33 to 45 or from 45 to 33.-------- But first try freeing the 33 to 45 switch button.It must be getting jammed due to dirt or anything blocking it.---------- If that is not helping then try other things,---------- This will help.Thanks.Helpmech.

Does my turntable need a new cartridge? I have a Technics SL DD22 which hasn't been used in a while. I hooked it up to a Bose receiver which works fine (hooked up an i pod to it before) & it plays...


The output from any regular turntable is far too low for most amplifiers to handle. You need to either run the output through a pre-amplifier first to bring the signal up to line output levels suitable for most recording devices and amplifiers or run it into an integrated amplifier which includes the pre-amp stage.

If your Bose receiver specifically includes a turntable input then it has a pre-amp built in, but as so few folks use turntables any more very few devices have the correct input. Pre-amps are still easy to obtain and can be very cheap, but cheap ones produce a noisy and unpleasant output which is magnified by the amplifier. If ever there's a choice to be made, spend the money on the pre-amp and go budget on the main amp.

I hope that I've saved you wasting money on something you didn't need. Please take a moment to rate my free answer.

Here is the simple way of doing it:

0) Turn on TV.
1) Press and hold the TV button, light lights up, continue to hold.
2) Press and hold the power button, light turns off, keep holding both buttons down until light comes back on, release both buttons, light stays on.
3) Point remote towards TV the entire time you are programming.
4) Press and release play button, wait 5 seconds, if TV did not turn off press and release play button again wait 5 seconds. Repeat until TV turns off. (When your TV turns off, it was in the last 10 codes sent).
5) Press and release Reverse button, wait 2 seconds, repeat until TV turns back on.
6) Once the TV turns back on press and release Stop button.
7) Your Remote is now programed! Test it by pressing the power button, volume, mute etc..

Technics SH-AC300 Connection to Power Amp & Pre-Amp


Hi!
The problem is, that your SH-AC300 needs an amp with 5.1 input (but no decoder). For this purpose technics delivered SA-AX710.
So if you'd like to use your current equipment it would be impossible.
The only option is for you to buy 2 more Power Amps (SE-A900S), so that each of 3 amps would take care for one part of music. (one for FL, FR; one for RL, RR; and one for sub and center).
Another option is for you to buy SA-AX710. Then all the problems would be solved with it.

Technics ST-X302L tuner - Unit not powering on


i have the same unit and a similar problem, after a fall of the tuner on the floor while i was cleaning my room, first times the st-x302l was powering fine but after some minuts it quit alone.. now (i dont know why) it remains on but if there is an interruption of electricity it dont turn on anymore, it turn on only by removing the metal chassis and moving random the electronics.. i think it has some electronic contact or circuit break.. i brought it to a specialist in electronics and he told me the reparation would be too expensive so i prefer to try fix it by myself.
