Paul, You do NOT want to take one apart to this level!
It's never going to operate again. If you look at the lamp in the PIX you will see a white coil wrapped around the bulb. This is the tank for the 90Mhz drive and it sits cocked at a 45 degree angle. The lamp assy can be removed easily via 3 small screws and repaired or modified. The Lamp circuit is designed to put out a bit higher RF level and once the lamp starts it drops down a bit. I would question re-engineering the lamp circuit as it can easily reach 1.5X10-13th at 100 Sec stability and 5X10-14th at 100 Sec. with the filter mod. Unless you have a maser or BVA to compare against how will you know if any modifications are going to help or hurt? The only thing I replace even if it measures OK is the 1.33K resistor as it will "crack" eventually and change value. A 1.3K 5% 1W metal oxide works well.
