I'm currently working on a recap of a Motorola 19CT1 for a customer. The set is in very good condition and has been upgraded to the 21" CRT with the factory-supplied kit as many of this model had been. The 21AXP22 shows excellent emission and balance. The R195 plug-in resistor is open, but I temporarily subbed 8-ohms 20 watts for the 7.5-ohms, unknown-wattage original. Sams only lists a Motorola part number and the resistance, no other specs. Using a 3A fast-acting fuse, a Variac, voltmeter and ammeter, I ramped the set up to about 100V at which I heard audio, high-voltage and vertical sweep come up as I watched the ammeter smoothly rise to about 2.5A. As I brought the Variac up closer to 120V, though, the ammeter reached 3A at about 110V and the fuse opened before I could raise it to 120V and look for a raster. I'd have used a 3A slo-blo, but I need to go pick one up. The 3A fast-acting was the closest I had on hand. Here's a photo with the covers opened/removed.
