Hello All,
Do you guys think this speaker would be worth a recone? The cone is stuck solid so maybe just junk
This, as far as I know, came out of a series I G100 yamaha
I just picked up a series II G100-115 and rediscovered this speaker in my to go pile.
thought I would just ask your opinion on the subject before I throw it away.
thanks

The Newcomer's Forum / Yamaha G100-115 II reverb tank
January 24, 2017, 11:50:04 PM
Hello all
just scored a G100-115 series two
does anyone know what reverb tank It should have ?
the bag is still there but no tank.


Anybody own one of these ? If so could you take a look at your tank for me.
I found the service manual for the series 1 which called out the tank as an Accutronics 4AB2C1A
I also found the service manual for the series II which did not call out the tank. I thought maybe the Yamaha part numbers would match but they don't.
I called our local tech today and he said he thought that the tanks would be the same but he was not 100% sure.
any of this ringing a bell for anyone

thanks,

The Newcomer's Forum / Yamaha G-100 bluesy pedal?
July 18, 2012, 12:57:02 AM
OK,
Looking for opinions on a good way to make the G-100 bluesy.
(Bluesy to me means nice and warm and slightly over-driven)

Foot pedal?
anyone have a home built that does the job?
Tube preamp?
mods?
I tried the Digitech Bad Monkey (Me no likey) very mechanical sounding.

This is the G100-115 series 1 if that makes a difference to anyone. 
Thanks,

Hello to all
I need to install new input Jacks in my Yamaha G100-115 series I, (stripped threads on the jack making for bad connections.)
I have downloaded a couple of different schematics but am not fully understanding them
I think someone else has been in here before me and it doesn't seem to go with the schematic.
From the schematic it Looks like the NC connection on the low input just goes to ground but the NC on the High input just runs into the Tip of the low input connector?
Could someone point me in a direction,
Thanks,

OK update...
with photos

Looks like the High and Low jacks TIP gets grounded through the NC connection which is wired through the "High" jack ground connector. The "low" Jack has a wire, attached to its NC connector (see photos) that was covered by a bit of shrink tube, This was broken when I opened the chassis but it makes sense to me that it just connected to the NC of the High jack to ground the Tip of the "Low" Jack.
The High tip goes to I1 and the Low tip goes to I2 and the grounds just tie together on the board
I don't know if you can see it on the photos but it looks as though the wires have been re-soldered to the board
so...
is this the correct configuration?
The Left most jack is the one I replaced to begin with. It doesn't allow the plug to fully engage so I purchased another jack also pictured. will this be adequate for this application?
The original Jack is pictured out of circuit for reference

thanks,

Amplifier Discussion / Yamaha G100-115 speaker
March 09, 2012, 12:16:20 PM
Hello to all,
this is my first post here and I have a few questions for you guys.

I Have a Yamaha G100-115. I believe it to be a series I. It currently has a Peavey Scorpion S15825 installed in it and it has Surprisingly warm tone. It came with the original (blown) speaker? Yamaha JA-3802 included with the purchase. would it be worth fixing the 3802?
I see them listed as bass speakers frequently and also as organ speakers too which leads me to believe that its kind of a catch all instrument speaker rather than a guitar specific speaker

I understand that the Peavey is kinda middle of the road "guitar amp" speaker and I am wondering if I could do better.

what would you recommend to bring out that nice warm tone?


Thanks very much,
