Technics 1210 internal regulation mods

Ok, best then to solder as close to the earth returns as possible, so find a point that you can solder to on the underside of the bottom-left corner (looking from above) of the PCB. If that makes sense :scratch:

hi can you have a look at the photo I've attached, would this be a suitable place?? The area with the red arrow ??

<checks circuit> TP4 is ground, so that should be fine.

I am located in Richmond, VA and am trying to locate someone who may be able to install the regulation mods. I have been in contact with Paul who knows no contacts in the States. Apart from the forums help, his suggestion was sending the deck (sans arm and platter) to ACS. Any suggestions? Sorry to resurrect an old thread but I didn't feel my question was worth opening a new thread.

These guys should be competent enough to perform the necessary.

I'm assuming you just performed an online search. I am sorry if my question seemed basic it's just that I wouldn't have known who to ask let alone what to ask them to do. I was trying to see if anyone had any leads on someone to ask that may be familiar with the mods. I will try contacting them though. thanks

Hi Caleb,

You posted in the right thread as it keeps all relevant info together as a reference for others. Let us know if you get a result, as there may be others in your area needing the service.

Regards
Paul

I guess I should clarify (for my own benefit mostly). Should I assume than anyone with even a slight aptitude for electronics can effectively install these modifications, or should I be more discerning in my hunt for a qualified tech? I am just a woefully inept audio newbie looking for a little guidance. Thanks

No, this needs more than slight aptitude as he will need to know what he is doing. It involves cutting PCB tracks, soldering directly to pads etc. We've already had one member brick his circuit board from attempting the mods himself so get someone who is experienced in electronics to do it.

I must totally agree with Martin. If you do not have any basis knowledge of electronics
and an understanding of componentry and have had little experince if any with soldering; then do not even think about it. These mods require that you know what you are doing in regard to circuitry.
I must admit that I did have second thoughts and felt that it was a "bridge-to-far" after I first speculated that other DC supply voltages on the PCB could be upgraded.
Then Paul of course took up the challenge and did a good job in developing the volatge modules we now have available. However there was nothing he could do to make the job easy and devoid of any pre-requisite experience in circuit work.
