"So to shorten this story ...I sold the M-150's and just bought a Zeus...that thing is BIG...That big boy puts out some sweet sound."
Enjoy it, Keith944t. I just sold mine a few weeks back. You're in for a treat with that amp. It served me well. Do you have KT90s? That made an amazing difference, as did upgraded NOS signal tubes and HiFi Tuning fuses. Good luck.
