McIntosh C2700 or Luxman L38uC

Hey guys!

Reviving this thread, was wondering if anyone has used 12AX7 (ECC83) tubes instead of 12AU7 (ECC82) on the Luxman L-38Uc?

If so, are there any considerations/precautions needed?

I have some 12AX7 around for tube rolling, was looking to avoid having to buy more tubes XD

Any help is appreciated,

Thanks :)

Not a good idea to install the wrong tube. Stick with the 12au7

I'm looking for some tube recommendations as well.   I just received a used 38uc and it honestly sound pretty grainy.    12ax7 and 12au7 are do common though I thought I would try a new set
