I hate it when I do that (all too often).
In the next few weeks, I have a really good chance to screw things up... had to order an NTE 703A for a Kenwood 5150 receiver. Lots of extra wires to put into the wrong holes.
I really shouldn't need to repair this receiver at all.. I bought it for parts for the one I had already (missing knobs, missing thumbscrews, etc.), but the doggone thing was partially alive, and I just couldn't leave it that way. The amp is in great condition, the tuner section was all but dead (totally on AM, a tiny bit of signal making it through on FM), so I had to track it down. Found that signal was good going into the IF amp IC, but nothing much coming out. I bypassed the IC with a 100pf cap, and got a nice solid FM signal and good stereo (shows how doggone sensitive these receivers are!). So, now I ordered a couple of the IC's and will put it all back to good working condition. Sometimes I'm my own biggest PITA.
PS, the reason I bothered to get the first one was that I knew about this particular receiver from owning one back when I was about 21 or so. They're really hot tuners. Not one, not two, but THREE RF stages for FM and one for AM. Special broad tuned AM IF's for better fidelity, yet still have good selectivity. The amp ain't bad, either.
