Looks like another classical surplus store going away.

official site and notice:
http://www.blackholesurplus.com/

A good time for Road Pilgrimages to Holy Places, this weekend - FRI SEP 21 to SUN SEP 23, 10A-5P. and bring a truck.

As we know there are still many good things for AM hobbyists there.

December 2011 visit notes:

"At the BH I bought two Aerovox 2uF 5KV oil caps, but saw nothing larger in high voltage except two caps about 4"x18"x18" with one terminal as a 3" tall insulator and one as the case, probably intended for power line PFC use and these had no markings at all. Ed did not know what the values were so it was not a good bet to buy them and figure it out later. I am guessing they are for the ~12KVAC or so power line voltages and have small capacitance, high KVAR.

They still have a good selection of small to medium RX type power transformers, up to about 200VA. I picked up several 15-100VA isolation transformers, filament transformers, 24V transformers, and among the power transformers was a 3600VCT 200mA plate unit and two NOS UTC GC300's in boxes. Picked up the 3H/3.5A/6.75 Ohm/7.5KV filter choke. No reason to leave that there! Also got a couple of HV supplies, 12KV/100mA and 10KV/50mA. The 100mA one has 4 Eimac vacuum rectifiers in a bridge and is intended to charge an external capacitor. There is a 100KV/5mA hipot power supply there, recently unearthed. It is light in weight, a large red plastic box about 24" tall with two current meters. Toward the end of the day we drove to Flagstaff. Ed from the BH had warned that some bad weather was on the way. Pictures from the previous business trip to the Black Hole can be found here. Several of the items in thoise pictures were bought up not long after they appeared on that website.

There are still many 'variacs' and isolation transformers; 500VA and lower seemed common but a few were larger. Many of the items featured on the aforementioned web page have been sold, but there are plenty more like them."
