I got this for $50 on craigslist and I have ordered all the caps to restore it. The 21ep4 non aluminized Crt was original and weak. Emissions came up to 70% after a long worm up but takes about 7 or 8 min. each time I let it cool down. I was lucky to pick up a couple of old sets a Zenith and a Hoffman with beat up cabinets and the Zenith had a Sylvania replacement Aluminized 21ep4a that was good
I will post more Pics. when it is done
