Best place to get odd value Tv caps

[akent36]

Working on a 1964 Admiral 11 inch portable just because I like Admiral stuff, it is cosmetically perfect and has a good CRT, but finding that 1000 volt caps aren't readily available even from Mouser. Where do you guys get these things without running into high minimum orders, etc?

I buy most of my caps from Mouser they're the most affordable supplier I know. Select the capacitance, the rated voltage and all voltages ABOVE the rated voltage, and you'll find something decent. I regularly get 1.6KV caps from them.

Sometimes on 40s-50s sets you need to fudge capacitance from the old numbering standard to the new...For example getting .047 instead of an old .05, getting .033, .039, .047 instead of an old .04.

The old numbering standard was 1,2,3,4,5 and power of 10 multiples/fractions of it.
The New numbering standard is 1, 2.2, 3.3, 4.7 " ".
The old standard is almost completely out of production and expensive so always translate to the new standard.

I have had success using film caps in series. These are often selected due to the high pulse voltages, though the DC across them is less than 400 VDC.

For instance, a vertical feedback timing circuit has a wax paper capacitor rated .0056 @ 1.2 kV. This value .0056 uf or (562), is commonly rated at 630 volts.

If using two .012 uf (123) in series, that is .006 uf and within 10% of original, but voltage divides across those, such that each sees half of the total.

The best selection of higher voltage caps I have seen, without minimum quantity, is at Justradios.com

.0056 uF film caps are readily available at 1.6 and 2 kV DC from Mouser.
Not even expensive.
