Hey guys, I know I’m just a new member, but would appreciate any help for a damn old fool! I recently purchased a Fromel Complete mod kit for my BJ. I have a Blue Junior III 2010 (REVISION D I assume) and decided to install a Fromel kit, but have stuffed something! It powers on fine, light comes on, but I can’t get anything from the guitar. There is a slight stable hum that is a bit louder than before, which ramps up with the volume (gain), not the master. And also changes pitch with the treble, which it did do at high volumes before also, if you paid attention while not playing. There is also a pitch change when you touch the guitar input, or put the jack in, which used to be silent. In fact the whole amp was very quiet until I threw a spanner in the works. The tubes fire up and everything, but just no signal. No smoke from anything. The original large capacitor always read 6 volts after it self-discharged, and the new one read exactly the same. It’s the only thing I put in that is polarized (apart from the jack). I did accidentally lift the pad on the PCB when installing the new WIMA cap on the bass pot (C6), but I scratched back the lead and it seemed to solder on okay, that’s only thing I can think of that didn’t go as planned (or so I thought). To be fair, I’ve never seen a pad lift so fast. I’m no tech, but I live out in the sticks in Australia, so there was no real option but for me to do it myself. I did start an electronics degree when I was young and both my brother and father are electronic engineers, so I thought I would still retain some of the skills I had, but maybe not! First time I’d even used a multimeter for a long while. How can I problem solve this thing to track down the problem? I know it’s hard without the amp in front of you, but if you could give me some easy rookie tips, that would be great. The only vague instructions were with the input jack, so maybe I screwed that, but not sure how. I did the Fromel Complete for MIM (made in Mexico) set, which is: Replaced C25 main filter electrolytic cap with 100uF/450v. Replaced C5 with a 250pf Silver Mica Replaced C6 + C7 with .1uF + .015uF WIMA caps respectively. Put a jumper on the mid pot. Replaced bias resistor with a 33k at R52 Installed new input jack, not mounted to the board. I disconnected the trans leads and dressed them better and replaced them. This is the kit: https://fromelelectronics.com/collections/amp-mod-kits/products/bjr-mods?variant=776492411 Note: The white resistor is just to discharge caps. And I didn’t put the extra little cap in (disable ‘sparkle mod’) Here’s the schematic: https://www.thetubestore.com/lib/th...r/Fender-Blues-Junior-III-Schematic-Rev-D.pdf Anyway, thanks for your time... :?
