Naw just what I wrote in the last reply , I had to inventory some parts and print the labels for the drawer's today , I got a small order in today , just 300 pieces . I might slide one of those WB B4's off the board later and check it 3 times just to be sure LOL..... I got a few friends in...
Gotdoggit nonc' you must be in Ossun or Scott , yep I'm just a little west of you in Eunice..... I called my engineering buddy Bill , he was the engineer at my Coozan's radio station here in town , KBON he told me I was right to doubt myself , cause there's more than one WB and that's the code...
The board does have the SOT 23 packages on it that are in fact diodes , they are marked with the D42 ETC silkscreen on the board... This one and the others like it are marked Q153 ETC.... This R package has the Emitter on the top pin and the lower left is the Collector the bottom right is the...
Yes there are several on the board and it is a NPN transistor, like I said it's a R version and that's the one I can't find ..... I'm pretty sure I researched it right , but there's always a lil doubt in my mind , I'm tooo careful like that, I'm an OLD school tech from the late tube early solid...
Hello all , I have this transistor that I'm trying to ID and locate a source for it , I think I have it sussed out , but I want to be sure . As the picture shows WB then turn it sideways it says B4 , I looked in the SMD code book and it says the WB is a 2SD1383K , Nope not mine different...
Down here back in the late 80's and the 90's we would cut a trace on the board from the crystal to ??? and add a 6 - 80 pf trimmer cap ???? across the cut to get the full 10 Khz slide with a flip of a switch, I can't get the caps anymore but I'm getting close to it....I need to find out which...
I dealt with Dick Briggs a lot from 1988 to 1998. I would buy several thousand dollars of toys from him, he told me back then he wasn't in the best shape..... I lost contact with him after I closed my shop down / retired.....He was a good man for sure and very smart......
