FWIW, the TL's are usually well matched anyways, at least that seems to be the general consensus 'round here...i had mine tested and they matched within reason
i only mention this 'cause i saw an unmatched pair in the yard sale recently....save a few bucks and buy a better pre !
i can send you samples of unmatched TLs , even got a few shows on the archive i could point out for you ....pm me.
