Philips GA 308 - Help a Vinyl Newbie Out!

Postby kobat79 » 30 Jul 2012 14:02

Hi all,

First post here, be kind!

I'm new to vinyl and picked up an old Philips GA 308 turntable for €25 yesterday. It looks like it is in mint condition, however I don't know if it works or not! The person I bought it from said it should work but gave no guarantee would work...

It did not come with a power lead. That is what I am assuming the two pronged connector socket at the back is for. Any idea where I would get a lead for this?

In terms of sound, what do I connect the turntable to to get it playing? Does it need some kind of an amp or preamp? Where would I get something compatible with this tt?

I suppose the tt would need an overhaul generally. I'd be fairly confident about taking it apart and cleaning it etc. But are there any how to's you could point me to that would give me a better idea of what's involved? I assume it needs a new needle or cartridge? Whats the difference between a needle and cartridge?

Sorry for the stupid basic questions, but like I said, I'm a TOTAL beginner!

Here are a few pics. Thanks!

The power socket leads looks unfamiliar to me, not modern standard. But a shop specialised in vintage electronics should be able to help you out. :)

This turntable has a DIN out for the sound output, this is the round plug. It was common in the 70's but not so common nowadays. To get sound of it, this DIN plug should be connected to an amplifier that is connected to speakers. Now, it could be an integrated amplifier or receiver (amplifier with built-in tuner / radio section) with a DIN input for turntables. You could start looking for European vintage hi-fi amplifiers or receivers from the 70's. (DIN is a German standard, not commonly found on japanese hi-fi products).

You could also attach a converter, to convert this DIN plug into the more common RCA phono plug, this means two connectors (red and black) instead of one DIN. This would make it compatible with more amplifiers and receivers.

Note: Older 70's and 80's amplifiers and receivers usually has a built-in special phono stage for phonograms / turntables, which is matched to the type of cartridge in use (MM or MC). Newer amplifiers or receivers often lacks this phono stage, so if you have an amplifier or receiver without phono stage / input for MM or MC - then you need a special phono pre-amp between the turntable and the amplifier or receiver.

The cartridge on the Philips is a Philips 400 cartridge, it is of MM type so requires an MM input. The needle is probably worn out so you need a new needle / stylus. Replacements are available.

Or you could buy a new cartridge to replace it entirely.
MM cartridges are lower priced than MC's and gives good value for money.

Wow man, thanks so much for the detailed reply!

So my options are to look for a vintage European amp or receiver or buy a modern amp or receiver (and possibly a pre-amp) and connect using a DIN to phono adaptor? What are the make of vintage European amp/receiver that I should look out for?

Also, I'm on a bit of a budget so what would be the most economical option to take?

Any recommendations on a replacement cartridge?

Don't know what I'm going to do about the power lead. There are no vintage electronic shop where I live. I will have to research this a bit more.

@Alec124c41 Thanks for that link. I have downloaded that manual now :)

@smeg68 That looks like exactly what I am looking for! It seems that it is sold though. I have contacted the seller anyway and will see what comes of it. At least I know what I'm looking for now...! Thanks

Ok, so I finally had a chance to have a root around inside this turntable.

Took the platter off to reveal the remains of a melted drive belt. This thing was the consistency of tar, and just as difficult to clean off. Luckily I had a bottle of cleaner used for cleaning heat sinks off CPUs and, with a lot of persistence and elbow grease, this removed the gunk nicely. I suspect this turntable may have sat unused in an attic space for many years and my theory is the heat in the roof space during the summers may have melted the drive belt?

After having no luck sourcing a power cable for the turntable, I decided to try to bypass the old odd Philips socket and wire the power input direct.

Inside after God knows how many years since it was last opened. The existing connection from the power socket is visible in the top right hand corner.
Image

There are meant to be three screws holding the bottom cover in place but there was only one present when I went to open it so I'm pretty sure someone's at least had a look inside here before.

This is a close up of the existing wiring from the power socket

I unscrewed the wire that connects from the socket to the block connector. I then wired in a new power cable, made from a spare length of 3amp twin core power cable and a plug I had lying around, directly to the power-in block connector. The unit is double insulated so no earth is required. I cable tied the old wiring neatly and taped it up out of the way in case anyone wants to reinstate it in the future.

Image

After that I plugged it in, switched it on, and hey presto the motor works a treat :) All that remained for the moment was to give it a good clean inside and out.

So next I obviously need a new drive belt and a cartridge. Can anyone recommend the best place that I can source these?

Also, I'm looking at buying this amp/receiver - http://www.ebay.co.uk/itm/Sony-STR-11L-Amplifier-receiver-Vintage-Hi-Fi-tuner-amp-/310418726027?pt=UK_AudioTVElectronics_HomeAudioHiFi_Amplifiers&hash=item484665dc8b

Will this work ok with the tt? I know it will need an adaptor from din to rca for the phono input but that's ok with me. Not looking to spend a lot on an amp! Would like to get something from the same era as the tt.

You can get a belt from turntable basics, never bought one myself from this seller so someone else may offer better advice.

Well done for bypassing the AC inlet, those cables are a pain to find.

Regarding the amp, you may want to keep looking for a better amp and seller.

Cheers,

Victor.

You can replace the phono cable with one having RCA jacks. The end of the cable inside the tt is connected to a tag strip with clips, so it won't be a difficult job.

Thanks for the reply Victor. Is there anything I should be looking out for in an amp so? As I said, would like to get something from a similar period as the tt, if possible with a receiver for extra versatility, and I'm on a serious budget. Not after audiophile quality sound either!

Thanks for the suggestion LPfan, I never even thought of that. It certainly looks achievable, but I'm lazy, and there's a Maplin about 3mins from my house that sell a Din to RCA adaptor for a few quid. Think I'll go with that!

i recently purchased a 70's record player with a din connection, i cut it off and soldered two phono leads. took ten minutes, i was always told clean copper is best for conections.

Wow - I have a 308 with a missing power cord too!

I'm installing a NEMA 5-15 (USA) receptacle in place of the legacy power socket. On the legacy power socket, which is the 'hot' lead or does it matter?

(I was planning on not connecting to the NEMA ground as to not introduce any possible electrical interference?)

Thanks Kevin - of course my wire colours are different (mine's blue and above is brown). To physically confirm, the brown wire in photo above is connected to the vertically oriented power prong?
