I've been looking at the T-Bolts on Ebay for a while, but have been holding off buying. This post just gave me an opportunity to ask some questions. I've seen references to the TAPR group buy in previous posts. It obviously happened before I found this group, but am interested in the details. Things like: When did the buy happen? Which model T-Bolt was bought? What was the price? Was PSU included? Are any units still available? Is another buy planned for the near future? <snip> Probably best to contact Tom Van Baak direct at [email protected] C/P of some past posts: [time-nuts] Thunderbolt Group Buy, part 1... Tom Van Baak <[email protected]> Tom Van Baak <[email protected]>...AddMonday, May 5, 2008 4:55:21 AM To:Discussion of precise time and frequency measurement <[email protected]> BACKGROUND: About a year ago, when surplus Thunderbolt GPS receivers first appeared on eBay, several of us pursued the idea of a time-nuts group buy. We kept it fairly quiet at the time while we probed the source, verified actual performance, and negotiated quantity & pricing. Recall that the first Thunderbolts on eBay fetched prices on the order of $300 (I know, I bought the first one). Later the price floated down to the $200 level. Even this price seemed like a good deal for such a name-brand GPSDO. These almost new unused Thunderbolts are quite nice; with performance much better than shown on Trimble's web site. Last year about 50 of you put in "pre-orders" for a total of about 80 units. With that leverage we negotiated a deal with the original California supplier. THE DEAL: I'm very pleased to announce that TAPR is going to stock these Thunderbolts for us and handle ordering and payment issues. Note that TAPR is non-profit and our time-nuts list has a non-commercial, amateur and hobby focus. So you will get these Thunderbolts at cost. The group price is just $115 each. You get a Trimble Thunderbolt AND a nice universal AC input +5/+12/-12 volt DC power supply AND the mating 6-pin DC Molex power connector AND a BNC-F antenna adapter. I will advise you when the official TAPR.org Thunderbolt ordering web page is ready. For an example of what you will receive, see: http://www.leapsecond.com/pages/tapr-tbolt/ ORDERING: 1) Those of you who "pre-ordered" last year will get email this week with instructions on how to submit payment for the Thunderbolt(s) you previously said you would like to buy. 2) Those of you newcomers to Time-Nuts should expect to wait until the first batch has been shipped and TAPR is ready for you. There should be enough for everyone; so don't panic. Flat rate shipping will be about $9 (US), $23 (Canada), or $37 (international). Same shipping for 1, 2, or 3 units per box, I'm told. I hope you agree the wait was worth it. Whether it's your first Thunderbolt or not -- this is an amazing deal for any of us. A lot of work went into making it happen. /tvb [time-nuts] Thunderbolt Group Buy, part 3... Tom Van Baak <[email protected]> Tom Van Baak <[email protected]>...AddTo: Discussion of precise time and frequency measurement <[email protected]> Discussion of precise time and frequency measurement <[email protected] Thunderbolt group buy: MORE kits and NEW price. Recently, TAPR completed all outstanding orders of Trimble ThunderBolt GPS receiver + AULT power supply kits. Those of you who ordered should have received yours by now. Since the stock of both TBolts and power supplies was limited, some of you missed the opportunity to place an order or to order a second unit. Now is your chance. The good news is that the telecom salvage firm found more TBolts for us and today TAPR is again accepting orders. In case you're wondering, these are not coming from China. The bad news is we can't find a replacement vendor for those nice AULT power supplies. So we decided to offer this batch of TBolt's without a power supply (but you still get antenna and DC connectors, as before). There's enough information out there on compatible +5 +/-12 V power supplies that this shouldn't be a big problem (see FAQ). And it will also reduce costs -- those power supplies had to ship from Asia to All Electronics to me to TAPR to you.
