Vacuum Variable Capacitors Max-Gain Systems, Inc. offers a wide line of vacuum capacitors, both fixed and variable, at absolute lowest prices! We have many removed from equipment, from commercial or military sources, as well as new surplus. See item descriptions. All are fully satisfaction guaranteed. On receipt, if not delighted, contact us for refund or replacement, if available. All you ever risk is shipping! Our inventory changes constantly, and many items are not shown here. If you do not see what you want, please email your requirements. Flanges are required for mounting certain types of vacuum capacitors, both variable and fixed. See item descriptions regarding required flanges, if any. We frequently have these mounting flanges available for sale, either with capacitor purchase, or separately. (Inquire for current availability and pricing) Click this link for a listing of Jennings flanges, complete with illustrations and dimensions! (We also carry many Comet flanges.) We have available large inventories of spare parts for vacuum capacitors, including pullers, shafts, bearings, flanges, etc., even for obsolete types! We offer hipot testing and diagnostic services, (to 60,000 volts) and in some select cases, we can perform repairs and restore "sick" capacitors.
If you require capacitors not in our surplus or used stock, or require factory new-in-box stock only, we are an authorized factory dealer for both Comet and Jennings Technology, and can offer all Comet and Jennings new stock at BELOW suggested list pricing! If you have surplus motor-driven vacuum capacitors or variable inductors (such as were found in military antenna couplers) and wish to slow down the drive motor for more precise tuning, CLICK HERE for a link to an instructional page.
The Jennings CVCJ-1000-3D2363 has a range of 7-1000 pf, and is rated at 3 kv peak. Maximum current is 60 amps at 5 mhz. Weight is 2 pounds, 12 ounces. Diameter is 3.07 inches, length overall, including the 1/4" diameter shaft, is 7.5 inches. Approximately 22 turns for full travel. Shown with the Jennings type FM-2 front flange mount, which is NOT included. Hipot tested, and fully guaranteed. Price: $295.00 (capacitor only) FM-2 front flange is available at additional cost. Jennings FM1C rear flange (not shown) is also available at additional cost. $15 for "trimmed" version, or $29 for standard version. Sorry… this item is temporarily out of stock (both 3 kv and 5 kv). NOTE: We frequently have 5 kv versions of this same capacitor in stock. Inquire for current availability and pricing on 5 kv versions. ( Order Now! )
Jennings UCSL-1000-3D345 glass vacuum variable capacitor with 27.5 vdc motor drive CLICK HERE for a ..pdf file with some information on this capacitor (copied from a manual for the antenna coupler which used this unit). Also a hand-written control circuit sent to us by a customer several years ago. We think this information will be useful, but we can make no warranties concerning its completeness or accuracy. Rated Capacitance 7-1000 pf Price: $239 ( Order Now! )
The Jennings UCSXF-1000-15S vacuum variable capacitor is rated at 12-1000 pf, 15 kv peak, and 70 amps maximum continuous RMS. The shaft is 1/2 inch diameter, and requires 40 turns for full travel. Maximum diameter is 4.31 inches, and overall length is 9.937 inches. Weight is 4 pounds. Requires FM3B front flange, and FM2B rear flange, not included, but available at additional cost. We frequently have these capacitors in stock, as well as several very similar types with 700 pf maximum, 1200 pf, maximum, 1500 pf maximum, or 2000 pf maximum, at peak voltage ratings of from 7.5 kv to 15 kv. Inquire as to current stock, state your preference, and we will reply with currently available options. Your choice of available types, Price: $349 ( Order Now) "Out of spec" and "budget" capacitors: If you want the quality and performance of vacuum capacitors, but the budget just won't allow it, (or if you are just looking to save some money) we frequently have "out of spec" capacitors . These capacitors do not meet the specifications for the particular model . This can happen because of many reasons, but they are still perfectly usable in other capacitance ranges or maximum voltages . For instance, we might have a type that is listed at 15 kv, but tests good to 12 kv . In this case, we will not sell it to a user who needs 15 kv ratings, but if you need only 5 kv, 7 . 5 kv, or 10 kv, this capacitor would do nicely . If you want us to check our "out of spec" shelves for current stock, just tell us your capacitance range and voltage requirements (and current rating if you know it . . . or approximate power level) and we will let you know what we have available at steep discounts! "SCRATCH AND DENT" We also frequently have in stock many vacuum capacitors which have cosmetic blemishes such as dents, which would not meet our high standards for regular sale, but which still check good, both in range, and in their ability to withstand voltage . Some dents will damage or totally destroy a capacitor . Others, if they occur in just the right places, cause no harm at all . We have the knowledge and test capability to make these determinations, and if they pass our stringent testing, sell these units at discounted prices with our regular guarantee! If interested in these units, please inquire as to current availability . If you don't see what you wanted: These pages show only a fraction of the stock we have available . We have many thousands of vacuum capacitors, both fixed and variable, as well as vacuum relays . This stock changes daily . If you have requirements for items not listed in these product lines, please Email, and our knowledgeable staff will search our inventory . (Don't forget to give us your email address and contact information!) Ordering: To order, use our secure online order form, or call us Monday through Friday 7 AM - 4 PM Eastern time at 770-973-6251. You may also print the order form using your browser's print button and fax your order to us at 815-461-7730. PLEASE give us your email address so that we can easily contact you in case we have a question. Visa and Mastercard accepted! |
