Here are some high voltage (5kv-10kv) high value metal film resistors (100Mohm \ 220M \ 330M \ 560M \ 680Mohm) for sale,
I use these for tube mic builds with great results
Have two types:
1. R1–32-1 (330Mohm and 680Mohm) Thin-metal film high value resistors (10kV max voltage)
*the ruler is in cm
Modern production, excellent quality - High–value, high voltage thin–film resistors
All climate version - stable at wide range of atmospheric pressure and humidity - Operating temperature range from – 60ºC to 125ºC
Designed for use in electrical circuits of DC and AC current.
Maximum operating voltage: 10kV DC
5% \ 1W
Great for measurement equipment and for many DIY projects like tube condenser microphone builds etc.
Full Manufacturers info:
R1-32 - ??? ??? ?????
2. C3-14-1 and C3-14-0,5 100Mohm \ 220Mohm \ 560Mohm - vintage made in USSR (NOS 1988 - OTK 5 - top military grade)
Not too much detailed info is available on these, from what I read and can state for sure is that they are:
"Non-wirewound lacquered composition ceramic base resistors in metal encapsulation."
Not stating "carbon" in the data list I found, so I assume they are either metal film or carbon film, not sure if they could actually be carbon composition at this size \ value \ voltage esp. considering metal casing:
Excellent quality
Designed for use in electrical circuits of DC and AC current.
Maximum operating voltage: 5kV DC for 0,5W \ 10kV for 1W
10% 1W \ 0,5W
Price is ~4$\ea + quantity discounts
Registered trackable airmail shipping worldwide is 10$
Paypal is accepted
