New User Posts: 2 Location: hartsville sc | Hey Wizard, I want to compliment you on this excellent article, you really have gotten all of us excited about restoring our players. My first question is have thought about making the bushings/ idler wheel for resale? It looks like there area number of us that are in need of the same parts due to age of course.Also can you give me the number for the stylus that you used and how you hooked it up.I would like to also do this to my mondern system. Thanks as much Ron | ||

Board Moderator & Exner Expert 10K+ Posts: 13054 Location: Southern Sweden - Sturkö island | Thanks Ron. The idler wheel takes me several hours to make and I tried to sell one, but it seems like my price was too high (close to the renovated ones which you can buy in America). The stylus is a Pfanstiehl ceramic cartridge diamont 911-D7, it's a new stylus made in Japan. The stylus has an output of up to 1,2 volt, so there's no need for a preamplifier. The hook up is simple - you solder a RCA female on a short cable and connect it to the pick-up cables. You connect it to an RCA input on a modern stereo with a "T" connection for to have the sound in both speakers. | ||

Board Moderator & Exner Expert 10K+ Posts: 13054 Location: Southern Sweden - Sturkö island | Thanks Morgan, one must be really stubborn and half crazy to do all the work and research behind this project. Now when the record changer is working and mounted, I use it very often - it's a time machine you know, like back to the past. | ||

Elite Veteran Posts: 693 Location: Kangasala, Finland | Really nice work! Looks awesome and sounds great - as does rest of your interior. That thing is cool. I would love to have one as well. It sure beats the '56-59(?) Highway HiFi in everyday use. The 16rpm record selection kinda sucks... Not trying to steal your thread here, but is that front rubber mat original or repro? I had one like it in my '60 DeSoto but it fell apart. Only difference was that it was white with black diamonds. | ||

Board Moderator & Exner Expert 10K+ Posts: 13054 Location: Southern Sweden - Sturkö island | There might be one Phono Matic 500 record changer for sale Jan. The rubber mats are old aftermarket items - not from Mother MoPar, but kind of nice still. PM me if you're interested in a record changer. | ||

Board Moderator & Exner Expert 10K+ Posts: 13054 Location: Southern Sweden - Sturkö island | Thanks' for the kind feedback guys! You know the procedure; fix one thing and three other "problems" occur? I had my 7-button self seeking radio converted and with that, the possibility to use a mobile phone or other auxiliary sources for music - worked just fine, BUT - the output of the pickup was too low, so the radio took over when I used my RCA AP-1 record changer. This forced me to investigate how to increase the output signal of the pickup, as well as solve that the mono output from the record changer couldn't make a "short circuit" for the other auxiliary units. I had some great hints from Serge in this matter - thanks' my friend! The first test was with a simple pre-amplifier and that worked out just fine - the output is now approximately 2 volts between the peaks and the record changer output is hence stronger than the radio signal, which makes the record changer the "master" as long as it's on.

Board Moderator & Exner Expert 10K+ Posts: 13054 Location: Southern Sweden - Sturkö island | Here is a picture of the test circuit with the signal relay mounted. It has been tested and it works very nice. Now I must tidy up the cables and the soldering somewhat. I'll try to make a drawing and a component list later on.

Member Posts: 16 Location: Germany | Although this is an old topic I'm glad I found it. You really did a great job on this amazing restoration. I've seen your video on Youtube earlier but never knew what you actually started with. That thing was really crusty! After many years I finally found a nice looking ARC 2500 that was still in working order but unfortunately the seller's wife was not too careful when boxing it so it arrived damaged and is not working anymore. I'm looking for an owner and service manual and will need some parts like the "cushions" for the springs, the motor mount grommets and have the idler wheel rebuild because it's dented. The needle is missing as well, I'm not sure if those are still available or if it would be better to look for a modern replacement? I got the mechanism working but the arm is not moving towards the record. The seller said it did move when he tested it so something must have happened during shipping. The ARC2500 has a small, tar filled box which is a small AM transmitter. It broke during shipping but probably won't be needed since I like to use an auxilary input on my hidden aftermarket radio. Apart from this the motor mount got bent, the seller did not secure the mechanism before shipping, even left some records inside the unit, which made it worse.

Board Moderator & Exner Expert 10K+ Posts: 13054 Location: Southern Sweden - Sturkö island | The cartridges still exists, see pictures below. As for a modern cartridge, I don't think they could withstand the heavy needle pressure.

Member Posts: 16 Location: Germany | Thank you, that already helps a lot. I will try to find a cartridge like this. Do you have a service manual for your record player? | ||

New User Posts: 2 | Hi, First time posting here. This is an incredible restoration. Bravo! I have a similar record player in front of me. Unfortunately, someone has messed around with the wiring to the ON/OFF and START/REJECT switches. Would anyone have any reference photos of the correct wiring or otherwise shed some light on how this is supposed to be connected to the plug? Thanks in advance. | ||

Board Moderator & Exner Expert 10K+ Posts: 13054 Location: Southern Sweden - Sturkö island | I have mine connected like this. The schematic from the manual is the second attachment. Good luck with the restauration, those record changers are very impressive and works very good. A show-stopper, when people see them and hear them working they are amazed.

Veteran Posts: 148 | wizard - 2010-12-10 1:27 PM The measurements You are definitely THE man!!! I just acquired an AP-1 and, of course, it didn't have brackets. Thanks a million for sharing your measurements and construction techniques for the brackets. Re-inventing the wheel is never fun! Best of luck with your ride! | ||

Veteran Posts: 148 | I acquired an AP-1 recently that needed the attention of a knowledgeable technician. Through some online forum I located Lee Faber in California, who has been working on the AP-1s since he was 15 years old installing them through the local RCA repair shop where he grew up. The result is amazing. The black portion of the case looks 100% times better than went I sent it to him. A real master of his craft. He sent me a video but it won't load here for some reason. I'll post some pics when I get the unit back and before I mount it in my DeSoto. Now I need to use Wizard's measurements to create some mounting brackets and get it installed.
