4PR1000A / 8189

We frequently have available the 4PR1000A (JAN 8189), which is the pulse rated version of the 4-1000A.  The 4PR1000A is the "cream of the crop" of the 4-1000A's, tested to ex tr emely high voltages encountered in pulse service . We typically get Triton (Triton bought Eimac's glass tube division in 1998) and Amperex.  If interested in our removed from equipment / tested / guaranteed stock and pricing (based on brand and percent of new tube output under test), please inquire. Stock changes daily.

We also have many of the 4PR1000A which do NOT pass our stringent testing, but which still LOOK beautiful (an extremely impressive tube for display) which we sell for that purpose. Many have made very impressive lamps with this tube, mounting it on a wooden base, with white LED's or low voltage bulbs shining upward through the (very convenient) holes in the tube base. This arrangement gives the visual impression of lighted tube filaments, without having to actually light the tube filaments... something you would NOT want to do. These very beautiful but sick tubes are $25 each for Triton, and $29 each for Amperex, when available.  Order as 4PR1000A "dud", and specify brand desired. NOTE:  Currently out-of stock on Amperex.

Eimac YC-156, YC-156A, and 3CPX5000A7

We frequently have these three tube types in stock, though not all of the time. EMAIL or call (best) for current stock and pricing. Our tubes of these types are pulls from commercial service from working equipment, and are always sold subject to your satisfactory test (on a timely basis).  If not completely satisfied, we offer refund or exchange (if available) less only shipping / packing costs.  ASK around. Our reputation is unsurpassed. We do maintain waiting lists for next arrivals if we are out of stock when you contact us. (No obligation.) Due to shipping / handling concerns, we do not ship this item outside the 48 contiguous US states. Manufacturer's data sheet for the 3CX5000A7 is here: http://www.cpii.com/docs/datasheets/76/3CX5000A7.pdf   The data sheet is for the non-pulse rated version.  Ours are all pulse rated! No sockets are required for these tubes, a big savings in amplifier construction.

  • 4X150D / JAN 7035
