It sucks, but they may only have a small qty of the spares, and they keep them for those customers who paid full price.
However, I agree about the high price. That would be better than "go away" Didier KO4BB Sent from my Verizon Wireless BlackBerry -----Original Message----- From: [email protected] Sender: [email protected] Date: Wed, 16 Feb 2011 20:37:38 To: Discussion of precise time and frequency measurement<[email protected]> Reply-To: [email protected], Discussion of precise time and frequency measurement <[email protected]> Subject: Re: [time-nuts] SRS PRS10 problem If you want to write a turd note about their service, I will pin it on their door. These companies need to know the reach of the internet. If they had any brains, they would offer you a replacement at a ridiculously high price. -----Original Message----- From: Brendan Minish <[email protected]> Sender: [email protected] Date: Wed, 16 Feb 2011 20:11:37 To: <[email protected]> Reply-To: Discussion of precise time and frequency measurement <[email protected]> Subject: Re: [time-nuts] SRS PRS10 problem Right, to follow up on my own email I took it apart The lamp assembly has failed. In the PRS10 the lamp is exited by a strong RF field @ 150Mhz this is generated by an MRF134 within the lamp package The failure mode was caused by the growth of a substantial tin whisker within the lamp assembly which appears to have killed the MRF134. I made contact with SRS about purchasing a replacement lamp assembly but since I bought it on the used market they are not willing sell me a replacement lamp assembly. Frankly I am not terribly impressed with their response on this. Does anyone on list have a 'donor' PRS10 that might have a good lamp assembly that they would be willing to sell me ? Perhaps someone on list has a commercial relationship with SRS and might be able to assist me with purchasing it? Hoping someone can help out, My alternative is to attempt to source an MRF134 and have a go at replacing it but there may be other damage in there regards Brendan On 14/02/2011 18:53, Brendan Minish wrote: > Hello all > > My SRS PRS10 ( http://www.thinksrs.com/products/PRS10.htm ) Rubidum > frequency standard was power cycled a few days ago, since then it has > not achived rubidium lock. > I have tried a full rest and also further power cycles with no joy. > > The SRS RS232 application reports the following parameters that 'look > wrong' > ad3 (lamp drain ) 2.001 > sd2 (fet voltage set ) 255 > > ad3 at 2 (Lamp drain volatge 20V) would appear to correspond with the Rb > lamp discharge not beginning > > this unit is of course out of guarantee and came to me via Ebay about 5 > years ago, is anyone on list familiar with troubleshooting these units > who Might have some general ideas of how best to proceed with repairing > the unit > > -- 73 Brendan EI6IZ _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
