seti Posted January 16, 2006 Share Posted January 16, 2006 I just aquired 2 tube MONSTER monoblocks made by webster electric which it turns out also made organ amps for Allen/Hammond the closest relative to these amps that I can find are an Allen Type 90 mine just have more tubes/parts otherwise identical. These were PA amplifiers @ LR Central High. I bought them before I had seen them and got lucky. OMG they are heavy and I hate the thought of shipping them anywhere. Tube compliment is 2 x 5R4GY, 2 x 6550/kt88, 2 x 6SN7, 2 x 0D3(power regulation) and a single 12AU7 per chasis. If you counted that is 9 tubes per monoblock woweee zowee. Who needs lights when these are on? I have been researching the 0D3 tube and it is a very interesting critter can't wait to see them glow. The guy I bought them from gave me a name of someone to send them to but geez ship them anywhere? It would be cheaper to drive them somewhere lol...40-50lbs a piece. Oh BTW thats 90 watts per block for PA use by the time they are built for home use on klipsch they would have about 40-50 watts. Does anyone recognize these monsters? Any advice or information welcome. Quote Link to comment Share on other sites More sharing options...
cueman Posted January 16, 2006 Share Posted January 16, 2006 Hey, what's the the story on the industrial LS cabs? Put em' to use yet? Quote Link to comment Share on other sites More sharing options...
seti Posted January 16, 2006 Author Share Posted January 16, 2006 The La Scala cabs were perfect and THANKS AGAIN!!!!!!! That was so cool of you : ) I believe KaiserSetSay is drooling over them and saving money to fill them full of drivers and crossovers : ) I'm sure he will chime in onthis thread. I can see a day in the future when these amps are rebuilt and those La Scalas are ready to rock the block party : ) DefBlockParty LOL Quote Link to comment Share on other sites More sharing options...
pauln Posted January 16, 2006 Share Posted January 16, 2006 As we have discovered on this forum, the way to test the quality of amps is... how much do they weigh? Those trannys are huge! Pauln Quote Link to comment Share on other sites More sharing options...
3dzapper Posted January 16, 2006 Share Posted January 16, 2006 Those amps are killer!!!![]If you do have to ship them anywhere, the only way is bolted down in wooden box(es). Rick Quote Link to comment Share on other sites More sharing options...
Daddy Dee Posted January 16, 2006 Share Posted January 16, 2006 Fabulous amps! congrats! Quote Link to comment Share on other sites More sharing options...
mike stehr Posted January 16, 2006 Share Posted January 16, 2006 "Does anyone recognize these monsters?" Yup. My local friend had a pair of those. Some of the transformers were the square potted type on his if recall. I don't remember any selenuim rectifiers in his. His were Allan 90's, or Webster/Allans.....it's been awhile. You'll have plenty of headroom....... Quote Link to comment Share on other sites More sharing options...
seti Posted January 17, 2006 Author Share Posted January 17, 2006 I found this link of the Allen Type 90 which is not far off from these. http://www.audioclassics.com/detail.php3?detail=TYPE-90&nav=cat Quote Link to comment Share on other sites More sharing options...
kaiser SET say Posted January 17, 2006 Share Posted January 17, 2006 I'm in 100% compliance that these babies need bolted down for shipment! I also think they will look great in chrome with some nice gloss black trannie paint[] Hello Todd, the Indo Scally cabs are going to be my summer project this year, maybe Ian and I will be coming on line with both of them restored at the same time[] What a sweet pick up by SETI, he will have the best of both worlds when he finishes these babies a he now has a pair of the sweetest 8 Watt Sets I've ever heard and being built on Western Electric spec they are some of the finest craftmanship I have ever seen and I'm running 3 pieces of BAT gear mind you! I probably going to pick up a used BAT VK-60 to drive the Scally's unless something else catches my fancy. That Allen is very close to what I saw at your house the other evening[] Quote Link to comment Share on other sites More sharing options...
NOSValves Posted January 17, 2006 Share Posted January 17, 2006 Seti, Send me a good full size picture of the under chassis wiring. These amps look beastly! craigostby@comcast.net Craig Quote Link to comment Share on other sites More sharing options...
seti Posted January 17, 2006 Author Share Posted January 17, 2006 Craig, I sent hi-rez images and closeups of the underside. Quote Link to comment Share on other sites More sharing options...
seti Posted January 17, 2006 Author Share Posted January 17, 2006 Unfortunately most of the tubes were broken. I think these are ok but I need to get them to a tube tester. I think I found a place in North Little Rock that has one and hopefully they can let me know which are ok. Quote Link to comment Share on other sites More sharing options...
seti Posted January 17, 2006 Author Share Posted January 17, 2006 Does anyone know of a good sight for finding/buying schematics for tube amps? I have been searching the interent off and on but so far I haven't found anything. Quote Link to comment Share on other sites More sharing options...
boom3 Posted January 17, 2006 Share Posted January 17, 2006 Does anyone know of a good sight for finding/buying schematics for tube amps? I have been searching the interent off and on but so far I haven't found anything. Since these are organ amps, I'd look at the Organists Guild of America (OGA) site to see if they have a forum like this one. There are a fair number of DIY/audio hobbyists in the ranks (pun intended) of organists. Maybe one of them might have some info. Quote Link to comment Share on other sites More sharing options...
