Thanks KK Sir, Terrific. I already have a VRDS CD transport and a 1955 DAC for CD. Wanna build one more DAC for CAS to play 24bit/192k source files in living room.

Looking forward to a course to building a CD transport only, best with SACD and module to convert DSD to I2S to be played by the 1955 DAC.

Wish your great success in the first day of year of Dragon... then we'll have a new toy to play with.

BTW, my DAC 1955 MK2 intermittently displays 'no signal', though the co-axial is still 'locked'. Any glue? Anyhow I replaced a BG 47uf and a wima .001u cap in the digital receiver section (my multimeter always detects short circuit with these pair of caps) and hope the issue was fixed.

Thanks in advance KK Sir. It's been working more than 10 hours and only disconnected once for 3, 4 seconds. The TEAC VRDS transport is 15 years old and I also cleaned the co-axial output with WD40.

WD40 is also a cleaner to remove deeply accumulated filth and thus improve conductance.

Well, if we are using a microscope to look things up. there are always rugs and dens which prevent perfect contact. In terns of practical application, WD40 can be used to clean electronic and electrical connections. It is not a conductor, by all means it is not an isolator either.

My whole purpose is to clean up the 15 years old filth. I would have to worry if WD40 is a conductor and I didn't clean it up properly which potentially caused a short circuit.
