Tubed Ccda I V Amp For Tda1541 A Diyaudio

Tubed Ccda I V Amp For Tda1541 A Diyaudio The schematic is for the output of one tda1541a. for the moment i use two piggybacked dac's and therefore have 27 ohm as an i v resistor. i have my tubes including the first 470k gridbias resistor and the 100k gridstopper connected trough screened cables to the other parts with the ccs and lpf filter. You could also stack the tda1541's so you could use a 30 ohm i v. a single 1541 should be used with 30ohm. 5842 would drop right in the circuit with a change to the cathode bias thats the point. so would the 6c45, the difference is higher mu and half zout, you can look at as very close to a 437 or triode strapped e810f.

I looked at that sometimes, i believe consensus is 56r to ground for a single tda1541, so floating pins from pcb, 6 and 25, 56r iv resistor to gnd and then tubestage you had in mind, tube i zator diyaudio , groupbuys maybe, has 56r, others also came to 56r trying, but browse diyaudio . Hie there i have a reel intersest in the passive ccda preamplifier would it be possible to gett the power supply for the above project tubed ccda i v amp for tda1541(a) [email protected] kind reegards john. Click for the first part of the dac schematic (before the tubes). pcb picture: a forum mate’s implementation as mine is not ready yet. pictures of my dac coming shortly. as for the tube stage i decided to use a ccda circuit inspired by a post in the diyaudio forum. the sk170 is used to null out the dc voltage offset in the output of the tda1541.

Followed the same nos mod and decided to go ahead with tube output and passive i v conversion. also, applied a few psu filtering mods to that pcb (i.e. adding chokes and better capacitors next to the power pins) . also, the important capacitors next the tda1541 are all nichicon film foil radials. I also have a stock adcom gda600 (pcm63 op amp out) and an audio gd r2r11 (discrete) for comparison. all these experiments led to my work in progress similar chinese tda1541 (nos mode) board (bypassed op amps) > tube output > line transformers.
