    Good morning from GA!

    Hey y'all, My name's Gary and I live in GA. I've got a few photos of my audio equipment for introduction show-and-tell. Yes, there are 2 of those Dahlquist speakers, I've just got it sprawled all over the room trying to get it wired-up and didn't want a photo of the full mess I've got going...

    My system (Crown amplifier controversy busted)

    The first place and time I've seen a Crown amplifier was at the Dick's Sporting Goods in Homestead, PA while at work there. It's a Crown Com-Tech 210 used in the store sound system. Originally, I didn't know what this black box was as It had lights on it that read "SPI" which I knew could mean...

    Question on 1959 Crown SXA tube amp power supply, switching noise from half wave rectifiers?? 120hz hum.

    So I got this amp in a trade deal a few weeks ago, and after one issue of basically building it back from scratch, from a blurry schematic from 1960, I still am getting some 120hz hum when the unit is idling, with the inputs shorted. I just replaced the selenium rectifier, and that seemed to...

    Crown dc300 or d150?

    I recently got a crown ic-150 on the cheap and love it. I figured I’d give a crown amp a try with it for my garage system. I’m looking at the dc300 or the d150. Does anyone know if these are similar just with lower wattage or is the sound quality affected too. I don’t need a ton of wattage so...

    Crown PowerBase 1 slight buzz

    I'm never sure whether to post requests for repair insight in the solid-state forum or here in the DIY forum. Hope I chose wisely... I have the aforementioned amp, purchased new back in the 80s, and it has served me long, hard, and very well, six nights a week for several of those years...

    So I have the above amp powering my mains. Thursday I came home from work and my son was listening to music and shortly after he shut it off. I turned it back on about 30 minutes later and channel 1 had low output and sounded slightly distorted. I didn't notice it when my son was listening...

    Crown A-30 mono tube amplifier EL37

    These are somewhat rare and not easy to evaluate. The A-30 30 stereo version appears on internet searches more frequently. My guess:$500-$800. Anyone ever see these sell or have an idea of value?

    Crown D150A - Puzzled. Fixed itself, then distortion came back. DC offset.

    **Edit 7/17/21: Skip to Post #51** **Edit 12/27/20: Now seeing +800mV on Ch.2 output via DBT; Ch.1 is OK** All original transistors and diodes, new electrolytic capacitors. I'm seeing some negative DC offset on one channel, and my outputs from the op amp do not match the schematic. Various...

    2N3585 Replacement - Trust NTE? Or pay a ton

    DigiKey has NTE 2N3585 for $15/5 pack (here; datasheet). Mouser has Microchip 2N3585 for $31/each (here) or Central Semi for $12/each (here). Newark doesn't have any. Would you get either of the above, or find a suitable substitute NPN TO66 2A / 300V driver instead? If so ... what? I can't...

    LF Transducers & Crown D150a

    Hello all, long story short I am needing a way to properly produce 16hz, most woofers simply don't seem to be able to respond at that low a frequency. I plan to purchase a low frequency transducer and either mount it to a stud in my house or to the raised floor and power it off of a d150a II...

    Monitor Audio RS6 silver speakers; as good as you've heard (or better)

    Crown XLS series

    I'm considering pulling the trigger on a used (dirt cheap of course) XLS600 to drive a pair of EPI 202's. Is there any variance b/t the older XLS amps vs. the newer ones that I should be aware of? I'm noticing that the newer XLS amps are at least cosmetically different & some of power ratings...

    Crown ic-150 low audio output issue

    Hey guys, I picked up a crown ic150 preamp that was extremely dirty on the outside , but very clean inside. I hooked it up and heard nothing at all until I turned the tuner/amp and the preamp to nearly max volume, but it's still very quiet. There is no visible issues with any of the caps (though...

    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

    Crown; a victim of unfair generalization?

    In many forums I've seen no love for Crown amps. Crowns are often described as "reliable, but not very good sounding." However, while I've never owned nor heard any Crown yet, I found it hard to believe they're bad-sounding amps. First, Ken Rockwell's measurements suggest that Crown D-75 is a...

    Parallel-mono operation: why aren't many amps able to do it? What are the downsides?

    Bridging seems to adversely affect an amplifier's capability to drive low impedance load. An amplifier rated to drive a 2 ohm stereo load (2 ohms on each channel) is only going to be able to drive a 4 ohm (or higher) bridge-mono load. A 2 ohm bridge-mono load will more than likely destroy the...
