Estate find! NOS vintage carbon Morganite/Allan Bradley resistors new unused for DIY projects. These are the best natural sounding resistors for tube amplifiers. As stated Allen Bradley resistors are carbon composite, being made of an organic material they do have the tendency to absorb water from the atmosphere. This absorption can increase the actual resistance of the component, hence the slightly higher than normal tolerance published on this page. To fix this simply remove the water from the component and seal it. The best method is to place the resistor/s on a baking tray, set your oven to 80 degrees Celsius and leave in the oven for 8 hours. The secret is to remove the mositure slowly if you rush it it will become noisy in circuit. Once cooked seal the body of the component in Shellack (preferably the flakes) to stop any further water absorption. At the end of this procedure you will have a much lower noise, more closely tolerance resistors.
I was offered a 8 kg batch of vintage carbon film resistors mostly in 2 watt from Germany from suppliers like Rosenthal and Resista. These are unused NOS 1960's made resistors for repair jobs or DIY tube amplifiers. When sold it's gone!
New unused adapter from 12AX7 ECC83 (bottom) to 6N2P-EV (top). Price is per one piece. Helpful if you amplifier used expensive ECC83 or 12AX7 and you want to use these adapters with the much more competetive priced 6N2P- EV. For a pair you need to order two. The 12AX7 or ECC83 is a high MU double triode. The Russian 6N2P-EV is a near equivalent however has a different pinout, hence the use of a adapter!
Tube damper silicone o-rings shock absorber. A cheap way to silence tubes wich are vulnerable to microphonics for example preamp tubes with 'long plates'. Just put 2 o-rings around the preamp tubes to silence any ringing! Can be used on tubes like ECC81, ECC82, ECC83 and their equivalents but also for example on a EL84.
