    Rogue 88 amp NFB relay question

    Yes I replaced a lot of caps because of the overheating. I used 0.1uF Solen Fastcaps for the first coupling stage and 2.7uF Solen Fastcaps for the second stage. The owner is very pleased with the sound now. I replaced all of the capacitors in the power supply as they either already failed or...

    OP AMP polarity question in cassette deck

    I just completed the restoration of a Nakamichi 582 cassette deck, it had four NJM4558 opamps, I pulled them and installed sockets. Now I have NJM5532 in there. I understand the PNP/NPN difference on the inputs between a 4558 and 5532 (the 4558 is PNP input, 5532 is NPN). My question is where...

    Laptop with Daphile vs Wiim Pro for streaming only

    I have a 20 year old Acer Aspire that I loaded Daphile on and have used it with an Emotiva preamp (I sold the Emotiva) via USB. Now I have a Geshelli Labs J2, with USB, coming in which will go to my main preamp. I will be streaming Tidal and/or Qobuz and wonder if getting a Wiim Pro to use for...

    Rogue 88 amp NFB relay question

    The popping was due to an intermittent ground contact on the left RCA input jack. Someone replaced the original jacks with Cardas, which are slightly larger. He didn't drill out the holes so the shoulder washers could fit properly and fix the gap around it from the chassis. I could see the...

    Rogue 88 amp NFB relay question

    I was getting low output with distortion, I suspected something in the NFB circuit, which is why I asked the (silly?) question. My electronics training was almost 50 years ago and I changed careers a few years after passing the aCET etc. I do my own build and repairs and also for friends on...

    Rogue 88 amp NFB relay question

    Someone did a bunch of shoddy diy mods, including bypassing the output transformer center tap fuses. It over heated and took out a lot of components. Now the input tubes are overdriving and failing.

    Rogue 88 amp NFB relay question

    A friend just told me that it is to stop the thump at turn on.

    Rogue 88 amp NFB relay question

    I am working on a Rogue 88 amp for a friend and am wondering why the NFB circuit is controlled by a relay. Every amp I have worked on before always had a direct connection from the output to the input cathode. To me it looks like when the relay is engaged the output is shunted to ground. The...

    Recommendation for an equalizer or equalizer schematic?

    As I said, I am not interested in something that I have to use with a computer.

    Recommendation for an equalizer or equalizer schematic?

    I want to get an EQ to play with, it will go between my DIY 3wpc tube amp and DIY tube preamp. I will build one if I can find the right circuit (I can build from a schematic) or buying one is ok too. I use different sources and want to be able to tweak the sound better. I am not interested in...

    Is there much love for cassette decks here?

    Hi everyone, being a new member and a believer in all formats I don't see much about the lowly cassette deck on this site (unless I am missing it). There is a reel to reel forum, which is great, but some of the higher end cassette decks can come close to open reel or turntable quality. I have 3...

    My latest refurbishments

    Thanks, although I work in lab medicine I did spent 2 years in electronics school in the 70s. I use what I learned to build and repair audio gear for my own amusement. I am semi-retired and only work one day per week now and enjoying every minute of my free time.

    What Cartridge(s) Is Everyone Using

    I am using a Hana SL that has been upgraded by Andy Kim with a boron cantilever and ML stylus. The table is a modified Technics 1200 with an Origin Live Onyx tonearm, external PSU and Ian Mac bearing. I wore out the SL stylus and prefer the ML sound and having it retipped was more cost effective...
