  • Help, my newly build 5e3 is really quiet???

    I origionally posted this in the 5e3 forum, but just stumbled across this forum, and thought it might be a better place for the question. Apologys for the double post- im new here...

    Hey, i just finished my mission amps kit- a 5e3 circuit, with a celestion g12h 30, in a home made pine cabinet... Im a bit confused tho- i finished all the soldering, got everything else done, and switched it on... All ok so far... Then i started playing gently to warm up the speaker, all still ok... After about 20 mins i decided to crank it and hear that awsome tone everyone talks about... It sounds good, great in fact, but its alot quiter than i expected...

    This might sound daft- i wasnt expecting it to be really loud, but i cant help thinking- is there something i could have done wrong- maybe sent something to grond be accident somewhere, that would make the amp work, yet not give out full power? I compaired it to an epiphone valve junior through the same speaker, and the valvejuniour was noticably louder- its only got one power amp valve, and its rated at 5 watts- the 5e3 has two, and should be about 18 watts... What have i done wrong? Could there be a valve problem?

    Sorry for the long post, but im just left a bit confused and a bit gutted- i wanted to gig with this (my orange ad30r is too loud, and the epiphone valve junior to quiet, i thought this would be perfect)...surely it should be louder when fully crancked, i am able to have a conversation (normal talking- no shouting required)while playing?

    Im looking over the diagrams that came with it again, cant see anything wrong- any suggestions would be much apreciated, or even a way to mesure what power im producing- i have a voltmeter handy...

    Thanks for the time to read this, and replys will be greatly apreciated...

    Most certainly Bruce will help you as he always does and I realize he's quite busy but for starters what is the DC voltage across the power tubes Cathode resistor at idle ? A bad tube could certainly do it or something not making good contact or a wrong connection. Double check all of your connections especially around those pots.
