WTB Gorgar speech board

[slither]

Anyone have a working speech board for Gorgar...just had mine professionally redone...lasted a few games and same issue with static, no speech. It's like it's st 1/100th volume...the amp chip was not replaced. He put in new roms and it worked, but now back to same issue . I sold the game and guy wants to pick up next weekend ..time is if the essence lol Thanks !

Alternatively can anyone tell me where I can get the required amp chip ? I cant make out the writing on it, thanks

It would be a TDA2002. I just checked and all I have are incompatible TDA2030A's. You may be able to use a TDA2003 as well but you need to confirm this. If you touch the amp itself and you get a hum it's probably still working. The problem may be in where the speech gets mixed in with the other game sound.

Ronnie at the time marked runs through the speech / sound circuit on a System 7; I know you're dealing with Sys 6 but it's a similar set up it would appear.

Hi, since the sounds all work except the speech there will not be any problems with the TDA2002 audio amplifier.
Same amp is used for both sounds & speech.

I worked on this sound / speech board set recently as it had missing speech due to a couple bad speech roms. The old original masked roms with the brittle, broken & oxidised pins are notorious for failing . Replaced them with a fresh set of TMS2532 EPROM's and all the sounds were back. Replaced the main +12V filter cap too for added value & protection.
So, either one of the op-amps has gone bad (U3 specifically, an MC1458P) or the CVDS speech chip has up & failed.

Yes one amp. Apparently an out of production one as well.

I'm not seeing a 2002 chip on the speech board , or even the sound board..I think it's the 2 1458 p on the speech board...
