| Autronic:
Just pulled the board out and found the SCR. It's an S1008L. I would say the transistor recommendation is correct. Need to do a bit more diagnosis. Thanks Chris |
| RayRay:
In my opinion, unless it has sentimental value to you, it's not worth the bother! You could easily get a C245 station for $50 or a T12 one for $30 (from Aliexpress) and either would be a big improvement. |
| Paceguy:
If I'm looking at your photo I see a semi C337 not C357. I would think that it's a 2SC337 which can be replaced by a NTE 123AP which could be similar to the BC337. Both are NPN. |
| wasyoungonce:
BC337 is fine. |
| Autronic:
Thanks Pace, not only should I get my eyes checked, I should get my brain checked as there is no way a TO-92 device would handle the 8+ amps the iron would draw. It's a faulty SCR, the heating LED is on dim and when I short the anode-cathode on the SCR the LED brightens and the iron heats. To Rayray, yes, I am not sure why I would bother to replace a USD 0.60 SCR to keep my high quality Australian made soldering station serviceable when the Chinese are purveyors of such fine soldering equipment. |
