I've been debating swapping the capacitors in the Yaqin SD-CD3 I have to something more reputable. I was wondering if anyone could recommend a capacitor to try that would actually fit in the limited space.
For reference, here (link) is the insides. The blue blocks are what I'm talking about. There are 2x0.22uF and 4x0.47uFcapacitors corresponding to the input and output, respectively.
I was leaning towards either Mundorf Zn or Clarity Cap SA, if they fit. I was also considering testing the Dayton Audio caps since they are cheap and might be worth playing with.
I'd also like to extend this thread to mods on a Darkvoice 336SE to avoid making two separate threads. For reference, here (link) are the insides of that.
Attachment is the closest thing I have to a representative schematic of the signal path based on Google and visual inspection of pictures.
Some things I'd like to do to that include:
- Swapping signal path resistors with precision resistors
- Swapping 20W chassis-mount resistors to higher quality resistors
- Adding cathode bypass cap
- Swapping output coupling caps (3x10uF film per channel) with a larger nonpolar electrolytic (possibly bypassed with a film)
- Swapping headphone jack and potentiometer
- Swapping preamp output coupling caps (1x0.47uF film per channel, similar to the CD3) with a different film
- Possibly redoing wiring with something more substantial, if I feel adventurous.
Anyway, I just wanted to know if people had any suggestions for coupling capacitors to use in either application, specifically. Any input is appreciated.
