my preamp tubes seem to last for years. I have only fully replaced them once (other than when I was experimenting with other NOS and PSVANE 12AT7s) and I've had my pre for several years. I am gonna guess I get 1500-2000 hours from them? I do not leave the MP-1 on when I am not listening. My 6SN7s are NOS Tungsol tubes in the key locations..I find them preferable to stock.
