Vintage Tube Amp

Vintage UL tube amplifier- tested and working – all parts seem to be original. 5 tubes are GE, transformer and SPRAGUE all pictured.

Up for sale here is this set of 5 used vintage Sprague Black Beauty 160P capacitors. 22 uf 400v, and tests around. 23.28 uf, with fairly low leakage, so they should work fine at full voltage in an amp. This is an amazing set of caps. These are too big for guitars, sorry. If you have any questions, please ask. I have more capacitors and other vintage electronics listed–feel free to take a look!

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.

Up for sale here is this box of 5 NOS NIB vintage Sprague Black Beauty capacitors. The caps are all marked. 1 uf 600v, and test around. 1.115 uf, with very low leakage. They will work great at full voltage. Please see my pictures for details and test results. If you have any questions, please ask. I have more capacitors and other vintage electronics listed–feel free to take a look!

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.
