Members tlchase68 Posted November 26, 2006 Members Share Posted November 26, 2006 I have a Mesa Boogie F-30 (an awesome little combo amp), but it has a decent amount of hiss most of the time and flabby tones on the higher gain settings. I've read that new tubes may help resolve these problems, but I am pretty clueless on this particular subject. I'd love to get some suggestions for websites to review/learn or information from you guys on what to expect when changing certain tubes in this amp. There was a previous post that recommended a particular person and/or website as the place to go for replacement tubes, but I can't find it due to the disabled search function. I'd appreciate any advice and or comments on this subject. Thanks! Link to comment Share on other sites More sharing options...

Very true. I've heard good things about Dougstubes too.Have you had experience with kcanotubes? I've never heard of them.

I put a full set in a amp I used to have and they sounded great! Really brought the amp to life. Link to comment Share on other sites More sharing options...
Members mrweems Posted November 26, 2006 Members Share Posted November 26, 2006 Well i know the E34L's are easy ot exchange.. But isnt there somthing that needs to be calibrated or somthing? the power tubes or somthing? In the Eurotubes for a full retubing of a Marshall JCM 100 is 4 E34L's and then another set of somthing.. Does that other thing need to be calibrated? I know nothing.. Link to comment Share on other sites More sharing options...
Members puddinstone Posted November 26, 2006 Members Share Posted November 26, 2006 An amp should be bias'ed when changing the power amp tubes. Preamp tubes are fine to swap. You want to make sure you have a phase inverting preamp tube for the last tube (closest to the power amp tubes) so your signal in phased correctly (I think it just sounds wierd if you don't do it) That's all I know.

Members puddinstone Posted November 26, 2006 Members Share Posted November 26, 2006 Except for Mesa's or other "fixed bias" amps. They can't be bias'ed as it's already set. You should make sure the tubes are within the right parameters. Euro tubes site has some info on this I believe. Link to comment Share on other sites More sharing options...

Members mrweems Posted November 26, 2006 Members Share Posted November 26, 2006 Hmm so would it be easier to buy what you want cheaper from somewhere else.. Send it to the shop where you bought the amp for "under warranty" detail work, and say while your at it get him to put the tubes in for you..? I really don't want to pay someone $20 to put somthing in that takes 5 min. Link to comment Share on other sites More sharing options...

I went there to get my amp re-tubed and biased. (about a 15 minute drive from my house)Cool guy, tons of help. but the JJ tubes don't seem to be all that cool. Took the life outta my amp. Even after the tubes were broke in. Just my couple o' pennies. Link to comment Share on other sites More sharing options...

Members Prehistoricpain Posted November 26, 2006 Members Share Posted November 26, 2006 i'll probably get flamed for this, but i really hate jj tubes. all their preamp tubes are a muddy mess, with way too much gain. and the power tubes just sound dull, like a blanket is over my cab.

Members Prehistoricpain Posted November 26, 2006 Members Share Posted November 26, 2006 Originally posted by Remedy which ones do you reccomend/like ? well, for med-high gain tones,in my jcm800 a mix of sovtek 12ax7wbs and svetlana 12ax7s and sovtek EL34wxt's for low/medium gain tones from my traynors, i use all sovtel 12ax7wbs in one (great balanced sounding tube) with sovtek EL34wxt's and NOS phillips 12ax7's and svetlana EL34s in the other. this one sounds a bit warmer and less congested.
