It wouldn't be a problem to re-do that drawing specifically for the 150BT-B31, just a simple bit of number-crunching on the calculator and altering the text within the drawing. From what you've hinted at it may be that the power supply for the CRT circuit is a bit 'weak', the voltage 'sags' under a varying load. But one thing at a time...I'll get to it in the morning...I would do it now, but it's 40 Celcius in my office/workshop...time to shut down the PC...

Often the symbol on the display for low battery is too small to notice...then only to find you don't have a replacement battery in the house...a quick trip to the 711 is next...thankfully they're open 24hrs! If you're in a small village or really rural, you'll have to wait until the next time you go into town...luckily my nearest 711 is only 400m away...a couple of minutes on my old trusty 1980 edition bicycle...problem sorted...and a bit of exercise at the same time...though a downer when there's heavy rain, it is coming up to the wet season here...
