Philips Philicorda GM 760

I bought my first Philicorda around 1995 and then traded it for a Fender Telecaster about a year later. Probably a good deal then but ever since that day I have been looking for a new one.

A couple of years ago I then finally got hold of a AG7500 via a friend at work. It didn't seem to be working. But after a little soldering on the cables I got it running. However not playable in a traditional way. This one still stands in a corner waiting to be looked over.

About a year ago I then found my second one, a GM751. This one could not be tested where I bought it but since the price was more than right I took the chance. It sounded terrible when I first connected it at home but after a few hours connected everything fell in place without even opening it. This has been running smoothly ever since and has become my favourite organ.

A couple of weeks before Christmas I went to pick up my third Philicorda organ. This time a GM760 it's a spinet model with two manuals and bass pedals. And I didn't have the opportunity to test this either at pick-up but since it was completely free it wasn't much to talk about.

When I connected it at home everything, apart from the bass pedals and the percussion (fast, slow repeat) sounds, seemed to be working. The organ has a really warm organ sound with a marvellous plate reverb that is also possible to use on for example drum machines, synths or guitars when you use the Philicorda as an amplifier for external instruments via the connectors on the back side.

5 pole DIN input and output connectors on the lower left back side

I made a short sound demo on the parts of the organ that is actually working. First it's the clean sound then with vibrato and reverb added.



The problem with the repeat function didn't bother me to much until I saw this video where the repeat function is used (around 3 minutes into the clip) and I really loved the sound of it.

Therefore today I downloaded the service manual and opened it up to see if I could find some simple solution to the problem. I can tell you right away that my skills in electronics and in Dutch are about equal and it took me quite a few hours to get an idea of how things could be working in the Philicorda. The attempt to fix the percussive section was without any success. But I took some pictures of the cards, components and wires inside.

Compared to other organs there are plenty of space and pretty easy to get an overview of the things. Philips has also made several smart solutions with hinges and such that makes it quite easy to access backsides of the circuit boards, keyboards etc.

Here's some close-ups from the GM760.

The knobs to the left of the lower keyboard. Manual, Volume, Pedal & Balance.

The knobs to the left of the upper keyboard. Selector, Repeat, Reverbeo & Vibrato.

The far left part of the panel over the keyboards.

The voice selectors for the lower manual.

The first half of the voice selectors for the upper manual.

The second half of the voice selectors for the upper manual.

One of three circuitboards each containing four notes, loceted behind the speakers in the bottom section.

The power and amplifier part and perhaps something more that I can't recognise.

Hello Niels, mi name is Edgardo and im from Argentine, i have a Philicord in perfect conditions of use, do you know how many cost this type of organ? sorry for my english.

greetings for Argentine!

Hi Edgardo!
The price of the Philicordas here in sweden is next to nothing. The combo models go for aroind $100-200 but the spinett models are often given away almost for free. I got one fre and one for about $30 .
But they are real nice instruments and they might be more rare in Argentine.

thank you very much Niels!

thanks for this nice post niels
do you think that the tubes are all for pre-amp or some of them are for amplification?
i am from argentina too! haha
thanks!

hi niels!

i just picked up a GM755 and it is in very good condition, except that some of the pedals don't produce a clean sound. they crackle or have very low volume. i tried to get in to clean them, but it looks like i have to take a lot of things off before i can get to them. we put the organ on its side and got enough off so we could see parts of the contacts moving, but we can't seem to reach the area that the connection is made. the pedals sound better today than yesterday presumably because we've been using them, but it would be nice to get right in there with some contact cleaner.

do you have any ideas regarding how to get the pedals to sound properly?

Hi, Great Blog. I have a philicorda on which the g#/Ab notes are weak at the bass end of the keyboard, any idea which transistor I need to replace?

Hi to everyone there!

I am in the repair process of a Phillicorda 22 GM760/05S I suppose this is the same like GM760 in the electronics with some little differences in cabinet and stuff like that. The Cabinet is very bad condition (fungal in everywhere) and I am a carpenter too and I will replace ALL the with real HONDURAN MAHOGANY.

The organ sound is very soft volume and I would like to know if somebody have had this trouble and know the root of this problem. I will appreciate any help or comment a lot.
