I know its not the exact same amp.
I re-tubed my 5153 with Mesa 440s(basically the ruby 6l6 GC just in a specific bias range) before i sold it, In boogie amps i hate these tubes even with proper bias. but in the 5153 it made me reconsider keeping it more than once. sounded good much more balance then the JJ's (again to my ears, I'm a 6550 guy through and through)
Had a bad batch initially, but due to mesa's return policy store just exchanged them once they asked if they were faulty. no problems.
I didn't get a chance to check the bias before it sold but in the month and a half the tubes were in there i didn't notice any apparent bias shift. tubes sounded good properly bias'd and cold biased (well, as good as spec cold bias of 50% dissipation can sound, imho ofc.)
for pre tubes, JJ's are generally a safe bet. been wanting to try the mullard re-issues they seem to have a decent no microphonics ratings (the short plate 4004's)
