It seems that with each passing day, we seem to dedicate most of our attention on the older amps, be them Black, Blonde, or Tweed, but it stops there. Since purchasing a '49 Epiphone Century amplifier I have really come to love the natural / hi-fi sound of the older octal tubes which makes me wonder a few things. I understand that the biggest reason they were phased out was due to power handling. They just didn't push more than about 10-20 watts and at a time long before good house PA systems, that was not great. Fast forward to now and 10-20 watts run through a good house PA system works out well and is about the same as what would be called a "house playing or small venue amp). It also makes for a good studio volume. So, I am wondering if there is another reason that these octal tubes are not desired? I see that there are a few builders out there using octals again which really has me tempted right now. So, what am I missing? Why are they not being more widely used? I don't seem to have any problems finding vintage tubes for my amp...except for the one that uses a loctal socket which is not that common anyway. The desire is strong....talk me off the ledge if it is a mistake.
