Hi David.
The crushing could well be happening before the detector. I'd be looking at each stage before the detector for distortion.
Remember on Mikes 900 I was short of two valves but feeding a high level signal into the last stage and penultimate stage I could get a very good picture indeed. In my case I used a high output distribution amp fed from an Aurora to accomplish this.
The amp could supply 15 P-P of RF at 45mhz so I could get a reasonable picture from the detector.
The valves that I did have were well down and there was very little stage gain at 45 Mhz.
Although I had the full set on my sheds floor, during the time I worked on the RF unit it was fed from a different supply for ease of operation.
