p.s. - Great job on your Admiral, 7"estatdef. In case anybody noticed, the cloth strap holding your CRT down exits its chassis clamping brackets at an angle slightly
towards the center of the CRT. The strap exits the chassis significantly
away from the CRT in the eBay item I won. that's the easiest way to tell mine's a 12LP4. I see yours is a 10BP4. The Admiral Roundie from Hell was a 12LP4. The chassis' look completely identical though...
