Good to know! I've been using these modules in projectors with no trouble, modulation is always quite clean, with no apparent instability so I'm probably not going to make any changes at this time.. Hopefully nothing adverse happens, but I ran all three modules for 50 hours running CW and 50 hours with a random signal on the modulation inputs before I installed them into their respective projectors to verify that there was no instability or degradation, and they passed with flying colors. That's all the experimentation my usage requires.. Maybe with my next modules I'll try a 9V supply to see if there is any noticeable difference in power, stability or modulation performance.
