The best preamp I’ve ever used (I consistently chose it over my Rupert Neve and Phoenix pres). In excellent condition and perfect working order. Brand new bulbs installed in the VU meters and power indicator. Additional replacement bulbs and tubes included. This will give you years of worry-free use. Hand-made by Rob Roy Campbell in Chicago.
