You are funny, one post insisting I rebuild an old amp and the next post insisting build new on a PCB, can't be both at the same time. 😆
So where am I going to get the money to pay for this additional PCB, taking in account twice followed previous advice?
Another option is provide a power supply designed for an EF86, a SL7 phase inverter, and EL84 or better, EL86 outputs. Then wouldn't need to do the calculations and design a power supply.
We are also waiting on your critique of the layout, understand you have other things in your life, so certainly not demanding it.
Incorrect. 😛 Well, kind of. When time permits and not working on the Elekor Labs, trying to get a phono amp into LTSpice and finding error (using a Type 26 as an output valve) and incorrectness (partly as the website has gone down so just the schematics), especially after reading @Merlinb 's book (need to adjust the RIAA for the valve preceding). I am finding I am learning more then just modeling an existing in LTSpice, seeing possible errors I made previously that need to be checked (just had other matters to tend to plus take a break).
This is the result, does not make sense. So why is it not producing a value?
Sure looks like the hand method is quicker and more accurate. The EF86 and the SL7 both consume 40mA, the EL86 174mA, plus your EL84 35mA quiescent current (assuming same for EL86, in a severe brain fog and unable to figure out how to calculate...), gets 249mA, in line with SPPs value.
Of course if there is a simple script or formula you can provide for an accurate result, look forward to seeing it. 🙂
By the way, did try the OPT just in case not understanding and didn't work out either.
After contending with the program, obtaining 1mA from the cathode of the EF86 (no values elsewhere), no values from the SL7, and the EL84 47,8mA from the anode, 6,6mA from the screen, and the cathode either -38,2 (average) or 54,mA (RMS as prior values). Are these values logical and reliable enough to use for the power supply design?
