Ibanez ValBee

Wait till you get one, and share with me more when you change different brand of tubes.. I am gonna change mine to some EHX ones!

sorry for late reply ripper.
yeah i definitely will... i plan to buy 1 or 2 tubes first, then go get my valbee:) then slowly experiment. i dun suppose its too troublesome changing tubes back and forth?
we should totally start some. "valbee-what-tubes-do-u-use" gang, haha.
 
the pre-amp tube swap is user-friendly. power amp tube replacement requires re-biasing.

hi.. tube amp 5 watter like valbee/champ actually dont need rebias due to chathode bias config. it self bias, as long as u put the same kinda tubes..different brand doesnt matter..:)
 
^ Ahh can someone confirm that?? I've got a tung-sol 6L6GC power tube waiting to be swapped in into my valbee! I've popped in a tung-sol 12ax7 already and the sound has improved quite abit IMO!

This is confusing, some people say need to bias, some say don't need...
 
only those who've done it can confirm, hope they come forth to offer some insights. if you're unsure, don't swap your power tube because if it really does require re-biasing then it'd translate to service charges (to re-bias your amp) on your part.

iam really sure this valbee chatode bias due to 5watt output for 6l6gc
quiet simmilar to fender champ, this type of amp which i already build 4 units,(from scratch) including tube hifi(similar power tubes,lower input gain,12au7) .
iam building tubes amp based on useful sites like ax84,
18watt.com...etc..

here's my blog which have not update for~2~3 month, :Ddue to busy for my next project, jtm50 ish kinda amp..
