The briefcase Seventeeners are fairly reliable. It has improved sound and a cooler chassis layout than earlier models. Troubleshooting is straightforward. Check out electrolytics and a couple of black caps in the vertical. Align the horizontal oscillator. Check tubes as usual.
The "box style" Seventeener 2 is a little more troublesome. It runs hotter and needs to have yoke wiring rerouted around the 15 watt filament resistor and damper to avoid fire. Virtually every original yoke (made by RCA-274 code) went bad. If it works at all, it must have been replaced. A 12K 2w resistor in the B+ power divider, caps in vertical, PC grounds, input electrolytic filter, AGC divider resistors, sound IF can and horizontal diode are all trouble spots. It will have some intercarrier buzz so don't spend a lot of time trying to get it perfect. The chassis was reworked for the first-year low end Predicta. That one can keep you busy.
