hi myles i have two of the new epi valve jr heads playing through an ernie ball volumn/pan pedal which allows me either amp or combinations of the two depending on pedal position the clean amp has g.t. 12au7-y/el84-s #8 hardness the dirty amp has g.t. 12ax7-c/el84-s #2 hardness they are each playing through identical 90w mesa black shadows (4x12 cab rewired as 2 2x12 speaker sets 16ohm) my question: with the dirty amp set at say 9 oclock on the volumn knob, the clean amp must be set at 12 oclock to achieve the same room volumn both amps are totally quiet, hum wise, when i'm not playing so i feel both are in good condition what in your oppinion is the reason for this difference in volumn at a given volumn knob position i really like this rig especially in light of the modest cost (2kids in college) but am most curious about this thank you much for any insight ray

hi again myles first of all my appologies...i misspelled your name in my previous post...i am red faced erichkopp's question is the flip side of mine the 12ay7 is the preamp tube? what would you use for a power tube as well for more headroom

hi miles i've just purchased the epi valve jr head which i'm quite pleased with at this point considering the modest price i'm strictly an at home player & even at 5w the volumn is excessive for my playing situation when i get it boosted to get the crunch i want which is usually between 12 & 2oclock on the volumn musicians friend is just a few minutes away from me & are a groove tubes outlet in the el84 which hardness would you recomend i start with to get this gain at around 9oclock on the dial am also planning on getting the chinese 12ax7 for it which they advertise as being very musical i am mostly playing an epi dot studio through this amp into a mesa 4x12 cab w/celestion 90w ceramics i don't think this is the speaker set i ultimately want for what i'm trying to do...but one thing at a time looking for the gritty progressive blues sound thanks for the info

I am not sure what you are asking here. If you are looking for parts, in the tubes and parts secion of my website there are the folks that I use. yes, specifically the parts you feel are the higher quality parts i appologize, i have read your site & somehow overlooked the parts section thank you for your response

hi miles thanks for the quick respones reguarding a schematic for my bv60h as a means of learning tube amps here's my plan to systematically go through this amp & upgrade each of the components which are obviously not the premium pieces due to the modest prices of the crate amps use it as a classroom make myself self-sufficient/marketable in this area... & hopefully end up with a perty good amp in the process kinda like when i started playing i also educated myself on the tech skills on squires & other inexpensive guitars before moving on to the better stuff now i have people coming to me wanting neck resets, fretwork etc. i have your tube amp book i will soon purchase your bias kit w/manual as well have a state of the art weller soldering station as well as a good digital multi meter i know from reading another of your threads reguarding the tweed amp replications that the belton sockets are a preferable brand for quality construction who are the other mfgs of the components i will be needing for this endeavor...caps etc where may these component items purchased any other directional hints you might offer to expedite my learning curve would also be greatly appreciated thanks

hi miles just bought the tube amp book going to educate myself on repairs upgrades etc on my crate bv60h however...not one crate schematic in the book where can i find info specific to my amp to suppliment the tech info in the book? thanks
