    Hello from Alabama

    New on the forum, guessing this is the place to do the intro, I have been into music and stereo equipment for some time, not new to this hobby although new on this forum. I have mostly vintage Adcom equipment, running B&W speakers and a pair of Vintage Vandersteens too, anyway, looking forward...

    Adcom GTP 450

    The tuner light on is out on this unit. Is there a way to fix or someone who fixes this sort of issue? The remote control volume is not working as well which has been an issue with this unit. The motor apparently does not last long and on mine, I do not think it lasted more than 3 years. Any...

    Entry-Level High End Power Amps... Need Advice

    Hey everyone, I'm getting bored sitting around in quarantine, and so I'm giving some serious thought to purchasing an old (but good) solid-state power amp. I don't need one, but I'll do it just for the sake of fun and hearing something different than what I've got for a change. I'm sure most of...

    Absolutely blown away... Snell Type A V (5) Reference

    Could not be more jazzed. I inherited a set of aging and disabled Type Aii Snells from my father who passed away this year. Lots of deferred maintenance, woofers were shot, grilles were worse. They sound and look amazing after restoration, but were just not the right speakers for my listening...

    Adcom GFA-585

    I've been a longtime lurker, but I've finally got some questions. I picked up an Adcom GFA-585, that is in good physical condition. I tested the voltage across the speaker terminals during start up, and warm up, and had it stabilize well under the 30mV suggested by EBC Electronics. I have no...

    Replacing AV receiver with ?

    The more I reading I do in audio forums, the more I realize I probably made a mistake in purchasing a Yamaha TSR-7810 when picking up a pair of AR-90s to replace my JBL 4311s. I knew I would need an amp with proper power for the 4 ohm 90s, so I just found a receiver with pre outs to connect to a...

    Power Rating: Adcom GFA-545II Vs. Yamaha CR-1000

    So, I'm trying to figure out (on paper) which of these amps is more powerful. In their manuals, the power is classified in different ways. Is it possible to quantify the different in power output between these two amps from the documentation alone? Adcom: Yamaha:

    Best preamp under $100 for Adcom GFA540?

    Getting a new to me amp and am curious on what your opinions are on decent preamps for that amount. Trying to stay under $100. Doesn't have to have phono stage beings I have a separate phone preamp. Was tossing around the idea of a No sound "tube buffer" preamp. I know it's not true tube, just...

    Need a pre amp recommendation

    My son has a Crown PS-400 and an Adcom GFP-565 playing through his recently restored ESS AMT 1Bs. He’s thinking about upgrading his pre amp. He asked me about a tube pre amp but this is over my head. Any recommendations? Thank you, Gary

    Adcom GFA-555 Help Needed

    Hello, I picked up an Adcom GFA-555 with a blown left channel. As you can see, I've circled in red the burnt resistors (R1 and R7) and transistor (Q8). I'm assuming the problem is a blown output transistor, but I wanted to see if anyone has experience with this particular problem. If you...

    Nikko Alpha II / Adcom GFA 535

    Recently picked up an Adcom GFA 535 for pretty cheap to power my Nikko Beta II pre-amp, which I really like. The Adcom sounds good. There's now, of course, the matching Nikko Alpha II available locally, for about 4x what I paid for the Adcom. Is it worth going for the matching set?

    Integrated amp to power Allison 6s for small space

    Hello all, I'm looking to put together a system for my ( tiny - 8' x 8' ) bedroom. I'd love to build it up around a pair of Allison 6s - they're the perfect size, I really like the aesthetic & was bowled over by a friend's pair of 5s, so I'm pretty sure it's the sound I'm looking for. I've been...

    Made a new thread since the system changed so much. My "source" is a PC/PS4 Pro/LG OLED run though an Emotiva PT-100 acting as DAC and preamp / volume control -- USB for the PC, TOSLINK for everything else -- to a first gen Adcom GFA-555 (true Nelson Pass design! ;)). The reQuests are wired to...

    Adcom GTP-400 FM, AM low volume

    Hi folks, Picked up a GTP-400 well aware of the issues they have with the FM section - usually fixed by replacing a variable cap relating to the FM circuit. After reading many threads on this preamp I don't think that's what is biting me. Both AM and FM, while stations are locked and signal...

    Adcom GFA-555 with dead left channel

    Hey folks -- A friend of mine has an Adcom GFA-555 with a dead left channel. I'm pretty comfortable servicing tube gear and solid state not so much, but these Adcom amps aren't terribly complicated, so I'm taking a crack at diagnosing the problem and repairing it for him. I had a few free...

    SIMA W2002 vs ADCOM GFA-535

    I have been rocking a SIMA W2002 power amp along with an ADCOM GFP-555 preamp for some time now and have enjoyed it. I recently spotted an ADCOM GFA-535 for sale at a local shop for $140 CAD, which appears to be cheaper than the average going rate. I don't need two power amps, so I have no need...
