This is a KROHN-HITE model 330-M ULTRA-LOW FREQUENCY BAND-PASS FILTER. This unit has been in unheated storage for many years. It is not tested and is sold AS IS. There are frequency numbers behind that glass that can be read with a back light. Buyer to pay shipping on 33 pounds. Please email questions. We combine purchases for savings on shipping.
Vintage Krohn-Hite Model 330-A Ultra-Low Frequency Band Pass Filter. Powers on. Dial lights are working and tubes light up. Unable to test further. Unit is solid overall with some exterior wear as pictured. Knobs appear to work fine. The black output knob has some plastic chipped off as pictured. From an estate. Measures 18" wide. 13" deep, and 9 5/8" high. I'll also be listing a Krohn-Hite Model 330M band pass filter. Check out my store. Be sure to read payment instructions and no non-paying buyers please. Thanks! Virginia residents will be charged 5.3% VA sales tax. Also. Any buyer who picks up their item within the state of Virginia must pay 5.3% VA sales tax.
This is a vintage Krohn Hite 330-M Ultra low frequency audio tube filter in good working condition. Was used as a recording studio effects filter so it has 1/4" connectors added for easy connection. Great for use on vocals or for creating sound effects in the studio or can be used for many other applications such as laboratory work. Has Amperex Bugle Boy 12ax7 x8. RCA 12ax7 x2, Sylvania 12ax7 x1, 12au7's x3? GE 12ay7 x1, 6ax5, OG3, and 6au5 tubes. This thing is built like a tank. I'm guessing it would cost about $10k to buy something like this new. If it were even available, judging from the build quality. Powered by The free listing tool. List your items fast and easy and manage your active items.
