    ARC SP-14 stopped turning on (did I fry my preamp?)

    Hi y'all, long-time forum lurker, first time poster. I very recently came into possession of an Audio Research SP14, in very good shape from a very reputable dealer (online, but with a high end brick and mortar store). Worked perfectly fine, sounded great on CD, but realized the phono out...

    Can I Split HDMI ARC

    Hi, I have 3 soundbars with HDMI ARC inputs. I need to connect these 3 to one HDMI ARC input source. I do not have much knowledge in handling ARC though I have done normal HDMI splitting for normal TVs. Question: 1) Are there any HDMI ARC 1 to 2 or 1 to 4 HDMI ARC splitters in the market? 2)...

    AR SP-4

    a friend asked me to look at his Audio Research SP-4. "It doesn't work". A quick search shows that @ConradH has posted thoughts and even a very nice resto page here. And searches on AK found another post from him. I brought it home and heard something rattling in it. That can't be good. Cap...

On floor on marble stand is my 45 SET amp globe 45,s and 6J5-GT tubes with 5AR4 rectifier. Right behind is Heathkit W-3AM monoblocs, they are running...

    Current Analog Room Setup 45 SET with Arcturus Blue Glass 37-A Tubes

    When I got this amp it came with a 5 pin to octal adapter so a # 76 tube could be used in place of 6J5, I thought at the time that I wish I had some blue Arcturus 76 tubes, those are very hard to find. I have a collection of blue tubes and I remembered that there was a 76 like tube the 37-A...

    ...audiophile? Greetings, all. Wanted to take a moment to introduce myself. Troubaudior from the upper midwest of the U.S. I have been slowly dipping my toe back into 2-channel audio for music. One might even say I'm delving into mid-end. Not sure I will ever return to "high end audio"...

    ARC SP3A-1 Repair Advice

    I recently inherited this pre-amp and got around to checking it. After complete cleaning of controls with F5 faderlube and cleaning of connections / tube sockets with D5 DeOxit, and testing (good) all 8 tubes, I turned it on and found the following problems: 1. The tone-control-defeat button...

    Preamp Opinions--comparative attributes & bang for buck

    Hi all, I'm looking into upgrading my system and it's time to go for a preamp. I have been doing quite a bit of reading about what I might want to look for. A lot of the stuff I'm interested in isn't typically available locally, so a listening test isn't possible apart from gaining a very...

    Phono on Audio Research SP-14 not working

    Hi All, I've just purchased a near mint A-R SP-14 preamp, with original boxes, and manual. Pristine. I would be very happy, but, I can't get a sound out of the phono stage. There's one 6922 tube in the stage, which lights up when powered up. The line stage works fine, btw. MM cart into the...

    Trouble with ARC SP-6

    Hi all, I have a late 70s Audio Research SP-6c preamp that I acquired in non-working condition from a family member several months ago. I took it in to my local tech, and $300 later I had it home and was loving it. Now I'm having issues again. When I power the unit on, I get a high pitched...

    ARC control for non-ARC devices

    Hello, I just purchased the Sony X900e and don't want a large HT receiver for my simple 2.1 setup, so I got the SMSL SA-50 PLUS. The receiver does great, and can easily power my setup to crazy volumes. The issue is remotes. The Sony remote is huge and has a host of very specific buttons, the...
