Read Brent Jesse's rave review of these affordable CCa alternatives:

"Rare German made Siemens 7308 tubes, in original Siemens boxes. These excellent sounding tubes are similar to Telefunken or Siemens Cca. Rated online in many discussion groups the best audiophile 6DJ8 type ever made, at any time. Gold pins, white Siemens label, halo getters, very low noise. These are VERY scarce in the USA, and are an excellent value when you compare this price to the prices of the Cca tubes."
