If/when you build that amp be sure to put a glitch resistor in series with the anode supply to the tube. Old 8877's can get gassy. I cooked my Ebay 8877 for three days with only filament voltage and the blower on. Also started it up with low voltage. Glad I had a glitch resistor because I still got an arc over. After that, though, it settled down and performs nicely.
Good Luck, Dennis W0JX/8
