Re: Drake R-4B build quality question


 

¿ªÔÆÌåÓý

I have never seen a poorly built Drake radio.

However, I had an interesting build quality issue in a 1951 Philco TV set. I did a full recap job on it but still no high voltage. It did not take me too long to determine that the wire from the cathode pin of the horizontal output tube was properly inserted, bent around the pin, cut but never soldered. It had been this way for over 50 years without having been previously discovered!

This must have been the ubiquitous ¡°hit-it-in-the-side-real-hard to make it work" set.

Philco, at the time, was well regarded for design and build quality. It just shows that a few things slip by even the best of them¡­

I still don¡¯t know why the QC folks at Drake did not catch this beast to which you refer. When I was at Zenith Radio, a very long time ago, repairing radios and stereo amplifiers on the line, I was always overseen by a QC manager who, while he knew little about electronics, knew a LOT about what Zenith products should look like and would not pass anything that did not look up-to-snuff. In fact, if I, or any other tech presented a significant number of nasty looking or poorly working sets for inspection, (or with unapproved modifications to make them pass tests) we would have been shown the door, that same day - no two weeks notice!

I got in a Drake R-4B (S/N 89xx) for repair this week that I consider to have quite poor build quality. I guess the assembler was having a bad day when he built this one.

I have found, so far:
?
1) unclipped full length component leads poking out of a circuit board, hanging in the air
?
2) a trimpot that was barely inserted far enough to reach the board pads
?
3) generally poor soldering, from way too much solder on most joints to at least one barely soldered joint on a component (this was probably the cause of the complaint)
?
4) jumper wires to the IF transformers almost touching the chassis or each other
?
I'm still going through it, but I thought I would ask, Has anyone else has seen a radio that is not up to the usual Drake standard of excellence?
