I've been using my Elrogs in my Lampy Big7 for about a month without problem. After George replaced the set that was about to fail (anode was glowing red in one spot) in my Audion Golden Dreams, I didn't want to risk it going forward. George thought a PSET was a riskier design for the Elrog. They were spectacular in the GD's.
I do hope that the Elrog remains reliable in my Big7. I have a Golden Gate on order and the Elrogs would be my preferred choice to run, assuming the GG mirrors the Big7 on tube choice. The Elrog has been the top choice followed by Sophia Carbon Princess 300B and then the WE replica 101D. Also looking forward to hearing the EML Anniversary Globe 45's that the GG is being provided with.
