Mighty Favog Posted October 27, 2006 Share Posted October 27, 2006 I've tried Parts Express and that was a no go. The only other place that Google came up with was some where in Buenos Aires (sp). Zettler AZ733-2C-24D <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> 10A 250VAC 10A 30VDC ¼ HP 240VAC 1/8 HP 120VAC It's the power relays for the "speaker on" of a Carver MXR-150. I can put them in so I really don't see the need to send it to someone. TankU !! Quote Link to comment Share on other sites More sharing options...
Guest " " Posted October 27, 2006 Share Posted October 27, 2006 Tyr this company. http://www.mouser.com/search/Refine.aspx?Msb=0&Mkw=rely&Ntk=Mouser_Wildcards&Ne=254125+1447464&Ntx=mode+matchall&Ns=P_SField&Ntt=*rely*&N=1323038%20254125 I think the critical pice of info is the voltage and current for the trigger coil to close or open the relay. Once known, you could actually put in a relay with a larger contact rating...main issue is to feed the coil enough juice to close it on one hand while not soaking too much juice on the other (this could stress the driver circut).

OldGuy Posted October 28, 2006 Share Posted October 28, 2006 Tom You could go to www.carveraudio.com . I was able to purchase a xtal for my receiver through them. Site has all the info. I had the same problem with my speaker relays. Took them out and cleaned the contacts with a relay burnisher. Now if it starts to act up I just operate the speaker selector switch to self clean the contacts. Norm Quote Link to comment Share on other sites More sharing options...

Someone boought out all their stock and is now in the buisness. It is www.carveraudiorepair.com and teh business is called HI TECH SERVICES. I shot an e-mail to them and got a reply asking if mine was 6-pin or 8-pin. Well, that all depends on how you look at it. There are 6 pins (2 X 3) fasion like a domino tile with 2 more pins off to one side. I told them this by drawing it out with a Word.doc file and sending that to them. That was about 5 days ago with no response. Wonder if they have a firewall for such attachments... Quote Link to comment Share on other sites More sharing options...
Mighty Favog Posted November 1, 2006 Author Share Posted November 1, 2006 Great!! HI TECH AUDIO has some that are actually a little more durable than the Zettler's. I ordered 2 at $20 ea. + $13 for shipping (ouch, but hey they've got them). I'll stretch out the life of the one's that are in there till they just flat out won't come on anymore then the new one's go in.[H] Quote Link to comment Share on other sites More sharing options...
