![]() put shielding in there, fender 4 wire humbucker with series/parallel push pull pod. Ive already modded my squier fat strat via, great mods on there. and now that ive moved came across it again and felt it had to have more to it. I got mine almost 10 years ago while wanting to start playing guitar. I know this is a somewhat of an older post, but googling for a nice mod of my pathfinder came up with actually only this post. I would suggest you to go ahead with a TDA2050 which is rated at 28W and is pin to pin compatible with the original. The 5532s I used were indeed "5532AN" - as to the power amp section the LM38 are probably too much for the cabinet and speaker, you would also need much bigger a transformer, as the 3876 is rated at 56 W. ![]() I'll let you know how it goes.Hi Again Rob, The VRs on the IC's is a great idea to smooth things out. It really sounds to me like the noise comes from the final amp stage. I've been looking at things in the LM series (LM3875, 47XX). I've also been sniffing around for better power amp chips, the one in there looks like it's had a questionable background. I'll definitely try your PS and PT tips next. I have some TL072s on order and some OP227s I'll try those as well. Frankly, I thought the new Op Amps cleaned things up a little but not a lot. I didn't put in sockets as I thought that might add to the problem. I couldn't get the hand picked "A" series, that might make a bit of a difference. ![]() I substituted the output chip - seems to me it was a TDA 2030 - with a TDA2040 and changed the original 8" speaker, putting in a 10" Celestion I salvaged from a wrecked Cambridge 30. I also added voltage regulators for the preamp section ( to avoid early clipping on the op-amps due to voltage drops when the amp is driven hard ). I replaced the original PT with a toroidal PT, with a slightly higher voltage and a better current rating, then I changed the rectifier to a 4 Amp bridge, this allowed me to increase the filter capacitors' value ( to improve the dynamic range ). I replaced the original op-amps with 5532s ( and it did help in lowering the noise, are you sure your 5532s are not crappy chinese fakes? ) and added DIP sockets for a quick replacement, but as a matter of fact I did the major mods on the PS and PA sections. I recorded it on my iPhone so don't expect studio quality sound.I own a Pathfinder 15R, and I agree it's great value for the money, still, I couldn't keep myself from performing some mods. I'm happy to answer any questions! Check out the demo video to hear the amp in action. As such, all items are sold as-is, so ask before you buy. I'm not a store, just thinning my collection.
