Hi, Is there some way to build a tube amp in a metal case, using the case as RF ground, and not have current flow out of the amp through the grounding conductor? (other than isolating that ground fro
For anyone that complained about no signature and no call sign, here it is. Could you give me feedback on the new layout, please? This is what the old layout was: https://ibb.co/HpMdDkY I realise now
Hi Jim, It is similar here in the EU as far as I know. A typical way devices, are constructed here is that the ground (including the case if made of metal) is not used as a normal current path in the
Hi Lukasz, I use a tube amplifier which I have built in 1975 in a no RCD environment. It uses a 3-phase HV power supply as well as single phase small power supplies. The amplifier is of course ground
Hi, It is based on a lm741 op amp (if I remember correctly) steering an N channel mosfet shunt regulator. The reference is two 1% resistors and a multi turn potentiometer (it only moves the voltage b
