gld Posted April 21, 2005 Share Posted April 21, 2005 Hey guys, those pics of the 50 mono's posted are very old amps. The new ones are much more refined and cleaner. Oh btw I did not do the glue stuff, whoever owned them did it, Gary Quote Link to comment Share on other sites More sharing options...
sunnysal Posted April 21, 2005 Share Posted April 21, 2005 gary, can you talk a bit about the 8 watt monoblocks? what tubes does it use? anything you can say about the topology? thanks, tony Quote Link to comment Share on other sites More sharing options...
Erik Mandaville Posted April 22, 2005 Share Posted April 22, 2005 Dean: You said: "I don't think he makes anything that's tube rectified, which as far as I'm concerned is the only thing out there that edges out the better switching amps. Based on what I'm hearing over here, there's no way in hell I'll ever own another solid state rectified tube amp." I'm sorry, but it sounds to me that your opinion concerning tube vs ss rectification is stated fairly clearly in the above quote -- which is what I was responding to. I wasn't intending to patronize, and don't think I worded my response in a way that was rude. I believe it's entirely within your rights to express your opinion concerning which of the two approaches is 'better' (for you), and you stated that opinion overtly. I don't agree with you, and I think I have the same right to say so. If you have never heard one of the amps in question, it might be fair to allow for just a little room for possibility -- that they still might be very good sounding amps despite the manner in which they convert AC to DC. Craig: I think the adhesive we see is silicone rubber -- I've used it for crossover work, too. Erik Quote Link to comment Share on other sites More sharing options...
Deang Posted April 22, 2005 Share Posted April 22, 2005 O.K, even though it feels like it sometimes, I'm aware I haven't heard every amp out there - so I suppose there might be an exception to the rule I've set up in my head. All I can say is the solid state rectified amplifiers I've owned to date have had a trace of hardness or brittleness in the upper registers. There is a touch of incisiveness to the sound, and the brittle nature of the notes makes the top sound a little smeared or hashy. The VAC, AE-25, as well as the Quicksilvers all shared in this nature. The QUADs didn't have it, Craig's modified Dynacos didn't have it, and neither does the QSC I'm using now. So, being the simple minded fool that I am -- I've deduced that tube rectified amplifiers and solid state amps with switched power supplies sound both cleaner and more natural.

Duke Spinner Posted April 22, 2005 Share Posted April 22, 2005 Dean .. are you using a class H QSC PLX ..?? these get great reviews in the pro forums .. i'm using a Ross switcher right now, instead of the Crowns .. Quote Link to comment Share on other sites More sharing options...
KCM Posted April 22, 2005 Share Posted April 22, 2005 Here's a pic of my Dodd 8 watt amp. This is a superb sounding amplifier with my Altec 19's. Quote Link to comment Share on other sites More sharing options...

Dean's using the 1602. Quote Link to comment Share on other sites More sharing options...
gld Posted April 22, 2005 Share Posted April 22, 2005 This response is to answer the question Tony posted on the 8 watt mono's. Just to let you know I only build mono amps now. The 8 watt amps are push-pull Class A amps. they use a very small amount of feed back to keep them in control, the early ones did not use feeback. It helped in the control at lower frequencies.The usable bandwidth is from 14hz-55khz @1db. The tubes are 5687's or some variation of that. You can use 7044's which are my personal favs., 7119's and E182CC's will also work well in these amps. Changing tube types will change the sound of the amps, so you can virtually tune them to sound the way you like it.The amps are self bias or cathode bias, so there is nothing to do except instal the tubes and listen. They use all Cardas terminations, detachable power cords. The amps are physically small (8"x 12"). They are reliable and stable giving long life out of a set of tubes, and the tubes are easy to get and inexpensive. The transformers are designed by myself and built locally as I can oversee the processes. The transformers are massive for 8 watt transformers, they are the same physical size as the transformers on the 50 watt amps! If you have more questions feel free to let me know.

sunnysal Posted April 22, 2005 Share Posted April 22, 2005 thanks gary for the clarification, I was not to familair with those tubes but they look pretty linear (the 5687 curves looked a little better in fact): regards, tony Quote Link to comment Share on other sites More sharing options...
playntheblues Posted April 23, 2005 Author Share Posted April 23, 2005 Sal did you get a hold of Gary? Quote Link to comment Share on other sites More sharing options...
sunnysal Posted April 24, 2005 Share Posted April 24, 2005 I did not call Gary because he did a good enough job of answering my questions here on the forum. His amps look like nice pieces BUT I am holding out for an EL84 amp...perhaps I will buy a dynaco ST-35 or a pilot SA-232 and rebuild it...regards, tony Quote Link to comment Share on other sites More sharing options...
Duke Spinner Posted April 24, 2005 Share Posted April 24, 2005 EL-84, EL-34 ... both very musical tubes ... lotsa Distor ..er, Warmth ..... i likem' both ... Quote Link to comment Share on other sites More sharing options...
