No Volume.

First, hey to everyone on the forums. I'm new to these here parts, so I apologize for already asking qestions/needing help. Hahah, anyways.

So, I just got my RM100 and played it indoors for a couple days. Loved it, thought it was the best thing ever. So, I take it for it's first show on Saturday and I turn up the volume ... only the volume hardly turns up. It gets slightly louder as you turn the master up, but it didn't even get close to touching the drums. With the level on the module maxed and the master maxed, it was still only bedroom volume.

Today I started pondering what the issue could be. So I decided to try and run my other guitarist's 6505+ preamp through my poweramp. Only ... I'm a total noob with loops. So, here is how we tried to decied if my volume issue was a module problem or a poweramp problem. (I know the poweramp pushes the volume so it was probably that but ... I can hope right)

We ran his preamp out into my seires return, and my send into his return.

This made everything nice and full, but I had control over the tone. Which makes me think my module is fine. To make sure we then did this.

I sent my slave out into his return, then he ran his send into my return.

This made him able to control the tone, but the sound was back to being quiet. Even when he turned his Post Gain up the sound was still very weak and only when I turn my master up did it get even close to being loud. However it still didn't sound like 100watts.

Sorry for being long winded. So I am assuming that my module is fine but my power amp is not. Am I correct?

Thanks,
-Bob

you have 3 modules- chances are it's not all 3 mods going out

did you check the bias? Tubes?

Good luck

I've only got 1. So that's why it's a mystery. I should have mentioned that, sorry.

I haven't checked the bias and the tubes seem to be fine. It's my first tube amp though so I'm no 100 percent sure that they are fine. All four are glowing nicely and there is no tube failure light being set off.

I would grab a voltmeter from Radio Shack and check that bias- it's an easy process and an improper bias is often the culprit

here's a link from jimosity that includes a manual that details the process and tube values
