[Boatanchors] Help with a Power Supply

[Bill Henderson]

IF you cannot get the original transistors and/or there are cost
constraints you could search possible direct substitutes:

I've used their products for years (decades -  ECG before them) with few if

The NTE line can be purchased through major suppliers such as Digi Key and
sometimes even your local independent TV/radio repair shop (do these still
exist?) may have what you need or be able to get it for you
