NOS Sprague Vitamin Q Glass Sealed Paper in Oil Capacitors
NOS Glass Sealed Paper in Oil Capacitors (Genuine Sprague Vitamin Q Type 196P)
Many players like the legendary tone of the Paper in Oil (PIO) Capacitors. The best known variety is the Sprague Vitamin Q. It has even become a kind of holy grail of guitar tone capacitors. These haven't been made in many years, and have gotten scarce and expensive. Some suppliers have even started selling newly made reproduction versions. Even then some of the popular sizes of those have now been discontinued. If you can find any New Old Stock Sprague Vitamin Q's anywhere near the needed sizes, expect to pay upwards of $25 in most other places. Even the newly made reproductions are going for $12-15 or more apiece, and many of them are only oil filled polyester capacitors anyway which isn't really the same thing. And the mineral oil that is used today isn't the same as the proprietary capacitor oils of the 50's and 60's which are now banned due to PCB's even though they are hermetically sealed inside the metal tube with a glass seal. And also, because they are made this way for high reliability, they haven't dried up and lost their values like the non-military versions might have. These are the real Vitamin Q parts, filed away in forgotten stockroom corners for decades.
I only stock a few sizes I have been able to find. If you need a different value, look in my other listing some of the other less well known suppliers that made equivalent glass sealed Paper in Oil capacitors to the very same military s pecification. Sprague just happened to be the best known one. I stock a few of the other brands and have many more chioces of uF values. As with all tone capacitors, the larger the uF value, the more highs are rolled off. These are all quite old, but have never been used and have full length leads, usually at least 2 inches per side or more. Available sizes vary from time to time according to what I can find. I test each one to specs, clean them up as best as I can, and add a length of vintage style cloth insulation to the leads before shipping. Make sure there is room for these in your guitar, the physical size is noted in the selection drop down box.
Price is for a single capacitor and includes shipping, (and bragging rights).
