Need Help with Gottlieb coil number and where to buy (hold relay, drop a card)

[beaky]

Hi guys,I need to find out what the coil numbers are for the Hold relay (coil R) & score reel on a Gottlieb drop a card.
The hold relay has burnt the coil wrapper so i cannot read the number and the coil on the score reel has been replaced before. It looks like the whole score reel has been changed so i am not sure if was replaced with the same type of reel or a different one. I just think it is strange that a coil that has been changed once before has burnt out again, looks like some one has repared the fault but not the cause of the fault.
The number on the score reel coil is  A-9154.

Also where does one buy these coils for an old EM?
Thanks in advance.

Dont know if these EM coils are any use, but you can always ask him if he has others.

I have bought from this guy heaps of times and he is a really good seller, good prices and doesn,t rip you off with postage.

ta, i will ask if he has any different coils.
the coils that controll the other relays beside the hold relay are A-9740 & A-9735.

Try here http://www.pbresource.com/coilgtb.html Greg at RTBB may have them but his site seems down.
This is also a good coil reference site http://www.pinballmedic.net/coil_chart.html

I still have some full score reels beaky and I'm sure I'll have the hold coil swell shoot me a PM Tuesday as Im working o. The monaro until then.

thanks to all that have replied.
now once i get these parts I will find what caused the score reel coil to fail.

Beaky, have a read on the pinrepair site - I think I came across something that suggests Hold relay fairly frequently burns out because it's on "all" the time and there is an improvement to be made by sticking a higher resistance coil in and (maybe?) converting it to dc.  Sing out if you can't find the details and I'll troll through where I thought I saw it.

Pretty sure the hold relay can be bypassed  - My 63 sweethearts has been bypassed.

I think that mod is ok up to 1967(Singalong)The DAC hold circuit is tied in with the tilt via a make/break switch.I tried bypassing the hold circuit on a post 1967 machine and ended up returning it to it's original state.Still may be able to do it somehow.

I have heard of people using the coin lockout coil.
Kill two birds with one stone, remove the coin lockout and replace it with a higher resistance coil.

Let me know what coils you are after, I still have a fair few Gtb coils and there is every chance I will have some if not all you are after.

I have got heaps of A-9735/R 20-4 and I could probably spare a A-9154.  I'll have to look for any others.

I am away for the next couple of days, send me an email if you are interested and I will get back to you asap.
