Glass test tubes suitable for a Zenith Porthole?
Since my blonde Porthole combo issue showed alignment issues when it was powered (sound not tracking with the picture especially) and the traps are all dangerously close to that metal tube I was wondering what tubes will work as test tubes in this chassis?
It's the 24H20 chasis with 16AP4 I found a couple of crts currently on ebay: http://cgi.ebay.com/ws/eBayISAPI.dll...=STRK:MEWAX:IT http://cgi.ebay.com/ws/eBayISAPI.dll...=STRK:MEWAX:IT Will either work?
