Hello there, I recently got this amp which needs a little work. I have not found a schematic for this or any of this series for that matter. Does anyone have any info on this amps or a schematic to share?? I'd really appreciate it. Thanks, peace.

I realize that your query for a guyatone ga-830 schematic is 4 years old, but I'm willing to bet you didn't find one.
I'm posting this to let you and anyone else who needs one know that I have original schematics for both the guyatone ga-830 and the ga-630, and I'll be glad to share them with whomever may have need.
Peace,
John

Hi, i was scouring the internet for a schematic for a GA-630, and managed to come across this post. Could you please do me a huge favor and share the schematic with me, I'm missing a tube, and the dealer told me that the only way to find out what tube it needs is to refer to the schematic.
thanks,
John

Hi John,
Could you please email me the schematic for the GA-630? I just picked one up and it needs some serious TLC.
Cheers!

If it's true that you've got the schematics for the ga 630 jlloyd1052 I would be super greatful if you could help me out with sending them. The amp, when it worked, sounded so great... super 60's. I was able to get alot of tonal range out of it, I miss it. Thanks for your time and help brother, Dan.

My apologies to everyone who answered my post about the Ga-830 schematic.
My mother passed away 28NOV11, then my wife passed away 12 days later. I have been a wreck for months, and am just getting back to some sort of normalcy.
If anyone still needs the schematic, please let me know.
I'll get it to you ASAP. I know how good these sound, and how tough it is to find any tech data for them.
Peace,
jlloyd

I'Ve acquired a Ga630 which was destroyed by during a fight in Vietnam (speaker and case totally) but the chassis came through ok. I desperately need schematics and any other information available. Thank you!
