Phaedrus Audio Electronic Tubes

We have been testing and using the VF14M and AC701 tube replacements in our mics for a year now and have had very positive feedback from our customers. These tubes are super quiet when compared with original VF14’s and AC701’s and the tonal response is very accurate. RMS Audioworks
