The experience gained over the years forced us to choose not to propose current production tubes because, as apart from a few rare exceptions, these prove to be significantly less reliable and with low performed in the face of historic productions.
The tubes were produced from eastern and chinese countries even in the period when large European companies: Telefunken, Siemens, Mullard, Philips etc. Or USA: General Electric, Western Electric, RCA Sylvania and so on. They were engaged in this market, but the quality peaks of the abovementioned brands were never reached.
Now that all of these brands have long ceased production, only (except for very few exceptions) Russian or Chinese valves remain at the low qualitative level
NOS and NIB tubes are for ever more rare and costly, but the acquisition of large stocks in many cases has allowed us to find high quality pipes that we can afford to offer at prices that can compete with the Current productions Even though they have been made from the best brand names dating to the 1960s and 1980s
We have therefore created this new category where we will go hand in hand to insert these tubes
