Philips GA230 (AG2230) help appreciated

Post by kora » 01 Jun 2008 11:46

While waiting for parts to arrive before I plug in a 1967 Philips GA230 I realised I didn't have much idea about how to set it up - the basics of arm balance, alignment, tracking etc. None of the audio websites seems to have elementary guides and I'd appreciate any help.

GA230

Hi, Kora, welcome!

This TT of yours seems to be similar
to this unit in the Philips Gallery:

Image: Philips AG 2230
ID: 3265
Poster: pluemse


An idler/belt drive according to the pluemse
description. He had to modify the headshell
to take a standard (Moving Magnet?)cartridge
Try PMing him: He will be best equipped to give
you further info in re rebalancing arm etc.

Depending on your amplifier you may also
need to change the DIN output plug into a RCA
type - or possibly need to organize an adaptor
first. And I hope the original rubber plattermat
came with the unit?

Good luck!

Thanks Delcam. I sent pluemse a PM last week, particularly to ask him how he did the modification on the headshell, but it doesn't look like he's been around much since 2006, so I was hoping to get more general information from my posting. I still need a stylus, belt and DIN-RCA adaptor. And as you point out, a new mat.

Kora,

Pluemse may respond later, with a bit of luck: Not
everyone does visit VE or their mails on a daily basis!

If the headshell is removeable (as it seems to be
from pluemse's pics): Could you possibly take it
off and publish some pics of underside of headshell
and the connecting surfaces in headshell & arm?
Also check if cartridge itself has any markings at all:
It may be still be possible to find a replacement stylus
for it. This only if it doesn't happen to be a ceramic
or crystal element..;( in which case it isnt really hifi
worthy...

Some further pics of the arm at the bearing post may
help to establish what system Philips used for track
weight adjustment so we can point you in right direction.
Normally the big counterweight can be moved back and
forth along the tonearm axis so one achieve a "neutral"
or zero position. With help of a cheapy stylus gauge one
can then slide counterweight forward to achieve correct
tracking weight. You just have to hope that the Philips
guys knew enough about proper alignment to make it
right for this particular arm/cart combo....

Thanks Delcam. I'm OK for a stylus, I think I've found a replacement at Mantra Audio. I've no idea what the two adjusting things are, in the photo, at the foot of the bearing post:

Here's a web link on that cartridge:
http://hupse.eu/radio/reproducers/AG3407.htm

For non-Dutch readers, it says:

"A Dutch Philips magnetic stereo cartridge from 1964.
The AG3407 is built into an aluminium shell with a mini 4 pin connection plug. The AG3409 too, but has a 65 um needle.

The resonant peak is 4dB at 14kHz, after which the frequency responce drops off rapidly.
The channel separation is better than 24dB, channel balance better than 2dB"


Tracking force is 3g it seems

Thanks Steerpike, the translation helps. As for a guide to initial setting up I came across this:
http://www.audiophilia.com/features/cartridge_setup.htm
Most of which would be lost on the Philips I think, but would I need a stylus pressure gauge and alignment gauge I wonder?

I'm OK now thanks, I learned a lot from the forum and the Philips and am now using a Thorens TD321 with SME arm.
