#HEADPHONE TUBE AMP FULL#
Good luck the design is certainly full of potential, just wanted to discuss potential pitfalls so you can be prepared and glad to see another dsavitsk insipred amp, he has been a groundbreaker with headamp designs IMO. It is a pain with building two enclosures and an umbilical cord, but worth it. Also I put the power supply/prefilter in a separate enclosure as it is very common for the PX to radiate hum to the OPT's. Linear Tube Audio’s amplifiers are based on David Berning’s patented ZOTL technology, an output transformerless design that delivers unmatched transparency and realism. If you’re still looking for more function, the DarkVoice 336SE OTL Headphone Amp is capable of powering headphones with up to 600 Ohms of magnetic resistance, as well as operating as a tube-based pre-amp for your speaker system. To be honest when I first plugged in my Grados when I finished building the SSHV-WE417A I expected to hear a little buzz or hum as most every tube amp does this with Grados, I was very surprised to hear a completely black background first time with the amp.
#HEADPHONE TUBE AMP TRIAL#
It is best to keep filtering to a minimum to keep the PS output impedance low, so you may need a little trial and error. It is certainly an interesting circuit to try.Īs far as filtering it really depends on your headphones, high ohm medium sensitivity probably OK, just if you plug in a set of Grados and hear buzz then think about the filtering, just wanted you to know it is a possibility to watch for. A headphone amp is a relatively low-powered amplifier that raises the low-voltage audio signal from a source device (be it a turntable, PC, or smartphone) to a sufficient level such that it. With a single CCS on two tubes it would seem the AC music signal would affect both tubes and cause a plate voltage swing on each of them. I don't know, it just seems that you have a constant current driven, no matter where or what the cathode bias is I don't see what would hold the plate voltage with either tube.
