heat

Hey guys, how are you? I got a Weller Wtcpt and it is not turning on or heating up. When plugged into the power source it does not do anything at all but it's been years since i used it. I am not an expert, could it be related to a bad-fuse problem? What are your thoughts?. Can you show me how...

Hello all, Thank you to all the members, both seekers and helpers, who make this website a living reference for hifi and audio related care. I just bought a Technics SU-8088 in its original state, no revisions or repairs done (supposedly, ever). I tried it with headphones, played 3 or 4 songs...

Hi guys, I have read here many posts about these "little beasts" running hot at the right side, just over the stabilizer board. I just changed some of very well known noise signal transistors in my beloved SX 5590, regulated the stabilizer voltages, checked the DC offset, and set the bias at...

Thank you all! I am restoring a Pioneer SX-828. While it's not my first time restoring a receiver, it is my first Pioneer. At this point, all the boards have been re-capped, new semi-conductors on the Main, AF, Head, Protect and Power Supply. The unit operates normally, protect relay...

Pilot SA-232 – Electrolytic Capacitors and Heat A couple of weeks ago, I was in the barn doing some cleaning and found my Pilot SA-232 stereo power amplifier, where it had been sitting for the last thirty plus years. I decided to pull it out of storage and see if I could get it to play music...

Short story: I tried recapping my receiver's power supply, it worked at first but the left channel died after I moved it a little, i opened it and noticed that one of the capacitors had gotten loose, I tried to reconnect it and now it won't power on. Question: What could've caused this? Is...

I have a pair of Dahlquist DQM-9 Compact tweeters that have pushed in cones for over 15 years. I totally neglected them, and apologize to all. One was rather mangled with a dent that actually was more of a folding over, and very irregular. It was as bad as anything I could describe. No...

From my knowledge in a basic way electricity and components like the cooler side. Now I do not mean abnormally hot just normal hot for what ever is being used. I am wondering if I turn my amp up to 8 (1-10) does it sound better "initially" than when everything inside gets hot 20 min or so...

Edit: Solved, see post #7. Here's a real humdinger. Yesterday, I turned on my NAD 7155, tuned into a local FM station, and left it on in the background. I stepped outside for a second, and come back in, and all I hear is static. It wouldn't pick up any stations at all ... I hit the FM search...

Hi guys, so my Yammie gets hot, like reeeally hot. I've been thinking it's time to give her a proper service and repairs and all but anyways are there any users here who use this amp and can confirm their amps have high temperatures too? Or is it my thing only? What if I will service it and it...

Still puzzled about finding the cause of the variable oscillation in the Audio board after recapping electrolytics. Low/high tap gets faster with more volume or more bass after unit is warm, no noise when cold. I'll be changing the bias trimmers to multi-turns, and I wonder if changing the...

Hey all, In an incredibly spontaneous and stupid act of self-sabotage I picked up Bose 1801 that isn't producing sound. As I understand it, there are three versions. The later ones do not produce fires as often. How can I tell which is which? This one appears to have LEDs, which I believe is...

G'day all, First off, I have chosen my name with care, which gives you an idea of my technical knowledge. I currently have a Luxman C-02 pre-amp (class A) combined with a Rotel RB 971 Mk II (class A/B) poweramp. A while back I was thinking about switching the Rotel for the Luxman M-02 thinking...

I recently scored a VSX-9900s for $130 on the bay, and replaced my newer Malaysian made VSX-914. There is no comparison between the 914 and sound quality produced by the Japanese made 9900s. I did try to score a D1S, but would have been another bill or more, and it seems more folks have...

I was looking to improve on my Yamaha RX-797 receiver, in my 2-channel system. It had to be remote controllable and be able to handle my efficient but power-loving Klipsch Epic CF-4s. Always a fan of NAD, I thought one of their integrated amps would do the trick. I nearly pulled the trigger on a...

Hello, I have been trying to recap a 1060 and have made excellent progress as the unit sounds very good now as opposed to when I got it. My question .... I am pretty sure someone has been in here before as the outputs appear to have fresh heat sink compound on them and they are Hitachi and not...
