Are Silvania ECC81s the preferred driver tubes on the various Earmax models? Again until today, I hadn't viewed any Earmax related posts but I'd started to pull several near NOS Telefunken tubes I had been keeping as backups for other speaker amps. I have several versions. But if Silvania's are THE tube to have, then that will make it easier.
My Dad & uncle ran a Radio/TV repair shop in the 50s, 60s, & 70s & because of me, my family has retained almost all of their old tube stock & I have full access to it. So I can almost always find any American or even some British branded tubes from that era or before. However some of them are no longer in "pristine" NOS condition. What ever I pull, I need to thoroughly test to be sure they still are in good shape. Most of the time they are, but I've had some big disappointments on what are now very rare & expensive tubes these days. It has saved me a bunch of coin over the years & fueled my continued interest in tube based amps.
So anyway since I'm suddenly an owner of that little Earmax amp, I really want it to have the ideal tubes to make it sound it's absolute best. As I said earlier, I really want to see it fairs against the Crack/speedball unit I had obtained for my Sennheiser HDxxx cans. I want a bedside unit & I have WAF issues with the large Crack amp.+ an iStreamer dac to feed it so the Earmax would go a long way toward cursing that problem if it compare well at all soundwise. The Crack amp is shockingly good for the price but it is really too big for my bedside needs. Oh we'll... I need a crash course on Earmax amps & tube combos! Any help or advice will be sincerely appreciated. Meanwhile, I'll try to read every Earmax related post I can find plus do more web searches.
