I bought my VAC 80/80 used in 1999.  I replaced the 4 KT88's in 2001/2002 with Ruby Tubes but never the 12AU7A.'s  The unit was in storage from 2003-2008 so the tubes aren't quite as old as they'd seem.  But I think it's time for new - better :)! - tubes.

I have a Sonic Frontiers SFL-1 pre-amp (just ordered a Siemens 12AT7 from Parts Connexion).  And Focal Profile 918's.

I've read good things about the EAT KT88's but the price is out of my budget.

I can just get the ones VAC is offering through their site.  But any other suggestions?

Thanks

Scott
