NOSValves Posted September 9, 2004 Share Posted September 9, 2004 This is on its way SET with hair on its XXXXX Discription The high voltage comes off the transformer and integral V-twin rectifiers, and is tuned up slightly with a small cap before being filtered through the large 10H choke mounted up top. Then it goes to the 3500 uF Sprague Powerlytic cap, which is a 450V cap seeing less than 300V for long life. Then it goes to the filter chokes for the drive stage and the output stage. In the case of the output these are the big 10H chokes slung underneath, and are the parafeed chokes. Each of them feeds a plate which has an output transformer stood off from ground by a 100 uF Solen cap to the top of the cathode resistor for that side of the 6336A. This is kind of like a 100 uF cathode bypass cap except that it puts a little local negative feedback into the output stage for a stronger, tighter presentation. The drive stage is SRPP 5965A tubes with both channels going through each tube and the 6.3V supply for the top tube floated up to about 200V, as I recall. Properly done, at any rate. The bottom 5965A shares the 6.3V supply with the 6336A, and is floated up to 20 or 30V as I recall. The drive stage couples to the 6336As through 4uF Sprague Black Beauty caps. I listened to a WHOLE LOT of caps in this position. Trust me, this is IT! The grid of the 6336A is DC coupled to ground through a 350H grid choke on a permalloy core to allow sourcing of positive grid current on peaks. As a result the amp makes about 10W on peaks instead of the 6W it should normally make. The way things end up the output taps are about 8, 4, and 2 Ohms. The two switchable inputs have an OFF center position and go into a 100kOhm audio-taper stereo pot, a cheap Alps. This goes to the grids, which have Allen Bradley grid stopper resistors that proved absolutely necessary for proper functioning. For safety there are also grid resistors of high value to ground, so bias isn't lost if the pot fails or develops a conductivity gap. The big fancy poly-in-oil caps up front are really nice caps and feed the drive stage. The smooth, organic sound of this amp is a characteristic of the milled graphite plates of the 6336As. The metal 6336s sound different, but not as good to me. I truly tweaked this amp for years. I believe it can be made to sound worse, but probably not better. It excels at natural fleshtones and is an ideal foil to "mechanical sound". John Day Quote Link to comment Share on other sites More sharing options...

radiob Posted September 9, 2004 Share Posted September 9, 2004 Nothing like 500 watts of SET. Im using these until Monday, If I like them on my VMPS's Ill be 5000.00 poorer. Quote Link to comment Share on other sites More sharing options...

NOSValves Posted September 9, 2004 Author Share Posted September 9, 2004 By the way the Manley is not SET its a push pull amplifier that works in Tetrode and Triode. This has nothing to do with SET. SET stands for "Single Ended Triode" not Push Pull wired in Triode. Craig Quote Link to comment Share on other sites More sharing options...
radiob Posted September 9, 2004 Share Posted September 9, 2004 The problem I have is that I want tubes on my VMPS, they require alot of power. The Manleys are about the cheapest thing I can find in SET tube for the power hungry VMPS Ribbons. Quote Link to comment Share on other sites More sharing options...

Deang Posted September 9, 2004 Share Posted September 9, 2004 Rob, don't sweat it -- you have the perfect duo for VMPS. I predict a tremendous driving yet luscious sound through those ribbons. Man, oh man, I would love to hear that combination. However, If you put those on the Chorus, and think you'll find the sound just a bit steely. Craig, now THAT's what I call a SET amp! Yowza, the thing actually has a parts count higher than six. Quote Link to comment Share on other sites More sharing options...
radiob Posted September 9, 2004 Share Posted September 9, 2004 Man Dean, do you have a laptop on you at all times?, 7700+ posts, I havent typed that many WORDS in my life. Ill have my chorus's crossover to you by the middle of next week, I promise. Quote Link to comment Share on other sites More sharing options...

NOSValves Posted September 9, 2004 Author Share Posted September 9, 2004 No I'm going to use it on Magna planers ! Actually my plan it to run this on the tweeters, a ST70 on the mids and VRD on the woofers so I will have a total combined wattage of 103 thank you.

thebes Posted September 9, 2004 Share Posted September 9, 2004 Ok, after you guys quit talking in Sanskrit, will you translate all this stuff into something morons like me can understand? In other words, does it rock, and roll or are you using it for weight lifting instead of barbells. Will it shatter windows and make angels cry? Inquiring minds want to know. Seriously, congrats Craig. We've got the pics now we need to know if it will make the Twins dance and get off my back for a change. Quote Link to comment Share on other sites More sharing options...

sunnysal Posted September 9, 2004 Share Posted September 9, 2004 craig isn't the 6336a a regulator tube? a twin triode regulator tube? you can see the tube specs at http://www.mif.pg.gda.pl/homepages/frank/sheets/138/6/6336A.pdf check out the curves...I am not sure how these would perform an amplifier output tubes...please explain. tony Quote Link to comment Share on other sites More sharing options...
radiob Posted September 9, 2004 Share Posted September 9, 2004 Craig, I am catching heat over in the VMPS forum on my Manley 250 choice. You have read the specs of my speakers and the Manleys, have you read the specs on the Ampzilla monoblocks? They are the same price as the Tubed Manleys but are SS. The veteran forum members are saying the son of ampzilla and ampzillas are far superior in dynamics, soundstage,and control over the Manley stuff. However none have listened to the Neo-Cassic 250s. Any help? Quote Link to comment Share on other sites More sharing options...
leok Posted September 9, 2004 Share Posted September 9, 2004 Tony, It looks like quite a performer: 30W plate dissipation, very low plate impedance, linear response. There's a Russian tube that Lamm uses that is the output tube for a MIG fighter power supply. Should be fun. Craig, I'm waiting for the review.
