Randall Solid State Amplifiers / RG13 headphone issue
« Last post by sh_leedesign on October 12, 2017, 11:11:54 AM »
I recently bought RG13 and I love the amp! Sounds killer with my Randall RC212. 

However, when I plug in headphones I only get the sound on the left side.

I tried 4 different headphones and they all have no sound on the right. I know the manual said some headphones will do this, but I would like to know why so I can fix the problem.

I have a newborn and the headphone is a must! Please help me find a solution.
Thank you.

It seems Randall AKA USMUSIC corp doesn't care about us and our $800 heads. Maybe they would care if we had bought the 2-3K heads

Same here! So far I've found this much out!
It does have a split bias. there are two screws inside the AMP behind the power tubes that say 2 outside, and 2 inside.  This allows for the use of different tubes. Try looking at the satans manual. it doesn't say much, but explains the two bias screws.I've emailed support, and have yet to get a reply.
Randall Tube Amplifiers / How to set bias on RD100h?
« Last post by Mike Shotton on October 04, 2017, 10:06:11 PM »
I'm swapping out the power tubes in my RD100H, but for the life of me, I can't find the bias trim pot inside the head unit to adjust the setting.  I've also searched the web for schematics of this head, but to no avail...  Can anyone help point me in the right direction?

Thanks in advance for any help/advice

I am curious about this as well.

Any info would be greatly appreciated it!
I haven't play rg 100sc or rh 100 g2, but I own a 1503 head about 2 years now and I can assure you that it's monster!! The clean is descent but the two dirty channels are absolute porn! You can play from classic rock to pure metal meltdown and with the help of 150 watt of power you can demolish small houses or kill your bandmates!! :P
Seriously now, the tones out of this ''cheap solidstate'' amp are awesome, the power is more than enough for rehearsals, gigs, jam...
If you find one try it and take it home FOREVA!!!!
