Hello Gene,
Like Jerry, I have been hanging back watching this saga unfold for now 57 pages! I will share a bit of my WOPL experience with you as well. I fell in love with the Phase Linear components when they came out. All through college I lusted for a 700b after hearing one that an affluent friend had purchased.
I could never afford one, but was very handy with a wrench. I had a chance to build a 1959 Panhead motor and transmission for a guy’s chopper in exchange for an almost new 700b. It was a 1976 700b, and I built the drivetrain for him, even up swap, in 1978. That was the only way I could “afford” a 700 back then. I still have that 700b and it is the flagship of my system, completely gutted, and fully WOPL’d. I joined the forum several years ago and had tucked away two 700b’s, and other “projects” to refurbish once I had time to do it. When Joe announced the Dual Mono board and the backplane assembly had proven itself, I pulled the trigger on the White Oak components. I never looked back!!!!
I have done 3 complete WOPL 700b’s and cannot emphasize the quality, and genius that is in these boards. I have repaired a lot of junk, brought it back from the dead, repairing pulled traces, and dealing with cheap components. The quality that Joe puts into every phase of the components, and the support you will get from the masters we have on board here is second to none! The boards are amazing, design, fit, finish, and overall layout. I had to build my own, as I have done with so many things in my life. There are some fellows here that are incredible to work with, and truly the best. Several have been mentioned to you, that would build exceptional boards for you. I built my own, and gained an intimate understanding of Joe’s design. Several family members were close by when I tackled my first backplane boards. I said out loud “this is freakin’ genius”, at one point. They all laugh now about how much I enjoyed that first experience….and the second….and the third. The proof is in the puddin’, and I listen to that 700b I traded for way back in 78, every day. Honestly, I have heard things on vinyl I have owned for over 50 years that I never did before. It literally puts an ear-to-ear grin on my face at least once a day, because I will hear a little bell in the background, or a singer breathe, a brush on the cymbals. The Dual Mono concept has to be heard to be appreciated. I listen to a lot of older 50’s and 60’s LP’s that are Mono. They have never sounded so good as with these amps, it puts the music in a class by itself. So as others have said (thank you Perry, and Jerry, rest of the gang) going the full WOPL treatment is a path you will never regret, it is that good.
There I couldn’t hang back anymore! Good luck Gene, really enjoy your posts.
