Hey mcinku
Plate voltage 462 and using 6l6
this puppy is sick and needs to go to the doc, I can''t fix it, I contacted Nik but haven't heard back yet.
It will all work out in the end. Take care, It is late and I have to work tomorrow.

I just watched a power tube die right before my eyes, something is amiss the noise level is way beyond what it should be and I am giving up. This baby needs a doctor. 

This is still one cool amp, and this problem will be cured, just frustrated

Doctor!!!

Hey All,
My amp seems really loud, When I got it it sounded wonderful but something is wrong now I think. I am not a tech but if I turn the amp up to say 6 on volume and 6 on master it is way too loud, I am talking about hum, it wasnt'nt there when I got it. The mid adjust doesn't seem to be ineffective and sound is buzzy when I overdrive it. I have 6l6's in biased to 38 mv.  I haven't done any mods it is stock and I am freaked out. Any thoughts. This is with all my guitars straight in no pedals. Help!!

Me too,
This is very sweet. A buddy of mine came over who is familiar with these amps and gave me an eq lesson. Right now I have no od on and the jazz on, I think bright and deep are off, I get mixed up because I am going to make a cab and right now it sits upside down. Unlike you guys I am running GT el34ls's that I cannot get close to even bias and it still sounds good, I know I just got it but I have never had an amp like this and it is so inspiring. I am not yet a proficient guitar player and but this amp makes me play better, or my bad playing sounds better. Cool :Smiley

I wanted to add that I am using a Lansing Altec 417 8c speaker in a generic open back (wide open) cab and it is the perfect match-wow!

Hope you are having as much fun way out there to the west of me poipounder.

I am not going to do anything yet. Do you mean the bias resistor because that is what I might have to change to get the range for the 6v6. I don't know a lot so this isn't something I will do right away but I will try it. Right now I am running GT el34ls's and I don't have a patch cable in the effects loop. My tubes are not a perfect match but I have to say this is one nice amp, I have never had anything like this before. My personal opinion, at least for now, I just got the amp so things will change, is that the el34ls's sound better to my ear than the JJ 6l6gc's. Oh and I am sorry I missed your reply, I didn't see it until now.

Thanks for the replies. I haven't had a chance to really play it, other than to know this amp is going to take me awhile to dial in. I like it but don't want to gush until I have actually got the sound I want to hear, but that is for another category. I biased it hot last night. Interesting, the pot to adjust has no slot for a screwdriver so I had to use needle nose pliers..is there a tool I don't know about. Tonight I am going to put some EL34's in it..can't help it I am a tweaker. Mcinku where do you have your OD pot adjusted to, and which side do you read it from to know where say 10:00 is, this may seem like a stupid question but I have to ask. I am pretty sure I got it right just checking. I did not get the gain I wanted, but like I said I did not have a lot of time to play with.
Also have you change that resistor by the trimmer, just trying to get a feel for what makes it be all it can be.
It is definitely a good amp.

Okay guys, I got it, it's sitting warming up. The amp I had that I could bias had two test points for each tube and a separate pot for each. This has only three, one ground two hot, and one pot. So I assume I adjust each one, I am just a little in the dark. I also am assuming 450 plate volts for now, because I don't fell comfortable measuring that yet. I will take it to my buddies house on Saturday and get him to show me the safe way. For now I just want to hear it I won't run it too hot, my ear is still good even if I am old
Hope someone is up still, would be nice to have this info, what a noobz with teh toobz eh?

I also have my tubes ready to plug in as soon as it lands 

Do you mind my asking what toobz?

You are doing a great job here Kitarist.
Lots of good info and nice people.

Sweet Jeffrey

Got an email from Nik today, my amp shipped
I bought tubes last week..I am ready, to play and tweak.

Thanks mcinku, I didn't know about that site having that info-big help.

You are right- A lot of work, my thought would be, I would give it a go, grab all I could find put it in one spot in a general way in categories of some sort, and then you(we) could edit it like wickipedia until we get it right(correct). I am not a tech so I would be unqualified to address that but could put all that has been written in one spot and then we do what I suggested above. I don't have my amp yet and when I get it it will take me some time to figure out controls but this could be a fun project to try and collaborate on with everbody.

mcinku, what tubes are you using, if 6l6, that is a warm bias(hot?) just curious, still learning, how does it sound. I have some JJ 6l6 gc's and a set of el34(groove tube el34s) that I like. I will try the 6l6's first.
