Vintage Tube Amp

Offered for sale are the vintage Sprague Bumble Bee Mylar capacitors as titled and pictured. Fully tested for both value drift and leakage. Detailed test results according to my Sencore LC75 Analyzer can be seen in the photos (in no particular order). This is a particularly nice group of caps that all measure within 10% of their rated tolerance, even though their original spec is 20%. Note: for those measuring caps with a DMM, my Fluke DMM shows these as being a few nF higher most in the. 040.043 range but I have displayed the LC75 results in this listing since it’s a calibrated purpose-built machine for analyzing capacitors to a high level of accuracy. This is just in full disclosure / for what it’s worth. The photos are of the actual capacitors you’ll receive. Please ask any questions before purchasing.

These were pulled from vintage equipment, have drifted in value, and show some DC leakage. As such they are being listed as not working even though they still might be usable in lower voltage applications. I randomly measured exactly a third of them (20 out of the 60) with my Fluke DMM, and the average value reading was 0.136mfd. These all came from the same source so it’s likely the others will measure around that same range.
