Greetings.
I wanted to start this off by saying that compared to most of the people reading this, I'm sure that most of my gear is definitely at the low end. Most of my audio gear is dedicated to my home theater setup, with gaming and movies in mind, in a 5.1.2 setup. Onkyo TX-RZ610 receiver, Polk Monitor 70 fronts, Polk Monitor 40 surrounds, Polk CS10 center, SVS Prime Elevation height\Atmos speakers, Klipsch Sub-12. So, nothing at the high end, just consumer stuff that sounds good for what I need it to do. I do also play music through it, with my only analog source being my B&O RX2 turntable (to which I'm about to add a MOSCODE super it phono stage).
I just wanted to put that out there to show where I'm coming from. I'd love to go down the road into a better system for music, but I've certainly never had the budget for it. But, and it's a pretty big "but", something fell into my lap yesterday that I could absolutely not refuse. I picked up a pair of Deja Vu Audio 300B Push/Pull Mono Amplifiers. For $115. Yes, that is what I paid. I picked them up, said "Thank You" and was on my way. The MOSCODE phono stage was had for an additional $40. I know the prices are enough to make someone suspicious of their origins, but they are from a widow who is selling her late husband's gear. I'm 100% confident that they are not stolen. So, I figured this was a chance to begin building something to listen to my records through. I figure that I'd bring my B&O turntable over to these, with my JVC AL-F3 moving back to its old place on the Onkyo receiver, and find a decent set of speakers that won't break the bank (but that's a completely different discussion).
It took all that to get to the point: One of them looks great if just a bit dusty. The other one has an obviously bad resistor. It is visibly burnt out (I am including a link at the bottom of this post to a folder on my Google Drive that contains images of the amp in question for anyone who wishes to take a look). All other components are visibly OK, but I haven't taken a meter to check anything else out yet. The resistor is a 25W 270ohm 5% resistor. I see nothing about it that makes me think it's anything other than a standard 25W cement resistor, but I'm absolutely 100% open to being corrected about this.
So, my question is: would the best place to start bringing this back to life be removing this resistor and replacing it with a like resistor, or is there any benefit to replacing it with something with an improved tolerance? My soldering skills are adequate for something like this. I've done enough SMD training/exercise kits that a large through-hole resistor inline w/ a couple of leads shouldn't present an issue.
I look forward to getting this up and running and hopefully I don't make any rash and/or costly mistakes along the way.
