Repairing an old Philips record changer, long post (Gezocht)
Hi everybody
Unfortunately I don't speak Dutch, and I hope you don't mind reading this post in English. I live in Norway and are new to old radios and record players. Where I live there are very little help to find when trying to repair old sound systems, and people in this forum looks very knowledgeable.
I have bought an old Philips radio from the late 1950's. It is in a fairly large wooden cabinet, the type people had in their living room, with jacaranda veneer, and a record player at the bottom. I have had the radio checked and repaired, new valves are put in, it works and sounds all right.
I contacted Philips in Norway and they told me it was built in Norway with Philips parts, and dates from before 1960, probably not later. I have spent hours browsing the web, but not found any thing that dates it more precisely. The record player looks exactly like this one I found on youtube, but I cannot find any model number on it. Every thing looks identical except for colours. From what I read on the web, it looks like Philips produced a record changer with this type of tone arm and and mechanism from the late 1940 to the late 1950's. A year or two before 1960 the tone arm was given a different shape, more slender and the record changing mechanism changed too. However Philips had several models in this decade, with lots of variations that complicates things.
Can you see the two round knobs / buttons on the front right corner on the video? These are still there in my record player, but connection to the rest of the turntable mechanism are missing. I think they have something to do with the tonearm's adjustment to different record sizes. These parts I would very much like to replace.
The tonearm has a one piece cartridge / pickup that sort of plugs on (tonearm = male, cartridge = female). I am afraid this pickup needs a replacement entirely, not just the stylus.
There are three wires that goes through the tonearm and I suspect one of them is grounding. Two red wires go to some point under the turntable and the third wire (copper) twirls around them.
The record player connects to the radio with two banana plugs. There is a sort of woven "metal stocking" encapsulating the two connection wires and the metal stocking is soldered to one of them. I have tried to figure out how this works, but honestly I really don't. I could not find the 1950's type banana plugs, but I found some gold plated new ones that fits. The plastic insulation on the wires are crumbling and they need to be replaced. I think the tonearm needs to be rewired too. Do you think I can use silver plated copper thread for the tone arm? This is the most easily available and used for current tonearms. I am slightly worried about how the grounding wire works, I will never be able to replace the twirling copper wire the same way it was originally made.
To sum it up:
1. Is it possible to find a new working cartridge that fits the tonearm?
2. Missing parts for the turntable, how to identify them and find them.
3. How to rewire the tonearm properly and new cables that connects to the radio.
Any thoughts and suggestions for this project is very much appreciated.
