The volume never dies completely. It just goes real low. And mushy.

Hello Myles. I have a mesa boogie dc-2 studio caliber. Plays good to about 20 min. Then it starts killing the volume til you can't hear it. Let cool down same thing. Replaced power tubes no fix. Any help is appreciated. Thanks ben

well i have replaced the EL34's with the 6L6's. I really can't

hear the difference. So I will be using the proper tubes 6L6's.

Out of curiousity what will happen if you do use EL34 in an amp

that requires 6L6's? If it damages the amp i don't know if I want

to buy this one cause it has had EL34's in it and i have no idea

how long!

thanks Ben

Myles

hello and thanks for all the advise you give.

I am looking at buying an Ampeg R-12 Reverberocket reissue.

the amp i am looking at sound great and everything works on it.

the question i have is there are 2 EL34's for power tubes.

All the info I can find say there should be 2 6L6's. It looks

like i could still put 6L6's in the sockets. has this amp been

modified? Is this ok will it harm the amp? if it was modified

how can i check it to make sure it was done properly? I like the way the amp sounds now so I would like to leave the EL34's in there if it won't harm the amp.

 

thanks Ben

Hey Myles

I have a mesa/boogie studio cal.

recently the low end has become loose or like

a low end flutter

is this my power tubes?

I haven't replaced them for at least a year.

Hi Myles

couple years ago I received this old amp from my music teacher.

I have no idea the year or model but I would guess 50's.

the brand is National.

It sound real clean but it used to shock me.

It only had a 2 prog plug.

I put in a 3 prong plug, connecting the ground to the

chasis. It don't shock me anymore, but I'm afraid something

else is the problem and this might be a dangerous fix.

also the tubes in this amp are not familiar to me

could this be a problem to replace them?

 

thanks myles any info

is helpful

[Feel free to ask Myles]

my amp is a clean machine now!

Hi Myles,

I seen in some early post you gave advise to tame an amp.

I own a mesa boogie studio caliber. a little 20 watt gem.

I love everything about this amp but I would like to tame the

clean channel. get a little more volume before it breaks up.

but I still want it to break up a little if ya know what i mean.

thank for any advise you can give.

 

 

Put a 5751 in V1. If that is not enough then a 12AY7.

 

 

 

so I put in a 5751 and all I can say is wow thanks man

 

what would happen if i replace all the preamp with 5751's

 

also I need to replace the power tubes

I think this amp is auto biasing too

 

the book say you have to buy mesa tubes but can I

get groove tubes?? they seem a little more quailty.

 

 

 

Preamp tubes in V1 and the phase inverter if 5751's would yield more clean headroom.

 

As far as output sets and Mesa to GT conversion look here:

which one is the phase inverter??

and do they go in order?? v1 v2 v3 ect....

the valve closest to the input jack is v1 i'm guessing.

cause it's the one that seemed to clean the amp up the most.
