Learning to bodge again..
I don't get it, caps are a consumable.
Yeah, but valuable - those tiny bypass caps- 4 new ones regularly sell for £120 on eBay! Crazy

Those were Reiki crystals! I'm sure this CDPs aura will be ruined now, you might be messing with tech that you don't understand :-s
Perhaps try putting the crystals in a wooden box with some copper plate attached to an earthing point
gfaw
There are red Blackgates in there! I'll buy the lot. PM me
No I'd listen to them. Never heard the red BP ones, although I am very partial to a type F or a VK....then sell it on Ebay for £1k?
I bet you didn't burn any incense before you opened the case either.Are you joking? He said they were crystals but they just look like worthless coloured glass to me - I have hundreds of the things, seller stuck them all over everything!
Perhaps I’m stupid or thick but I totally fail to understand what the antique valves do. Enlighten me please Richard! I thought I understood electronics but here

The external clock is nonsense, put it back in the case and give it a good local reg.
Is the Grundig philips cdm2?
I’ve never listened to NOS before, and I frankly think an external tube clock is a bad engineering decision, all I can say is that it sounds great
@Dan K I meant sell the 'earth box' you suggested at £1k. Probably enough crystals to make 10 of them. reckon about 100 quid in wood and copper sheet, plus about 1/2 day each to make. Can I have a commission for expanding the idea?
Ahhhn. now understood. No, all in the public domain@Dan K I meant sell the 'earth box' you suggested at £1k. Probably enough crystals to make 10 of them. reckon about 100 quid in wood and copper sheet, plus about 1/2 day each to make. Can I have a commission for expanding the idea?
The result was even better than I remembered & functioned flawlessly.
The CD104 uses a TDA1540 DAC chip which is 14 bit when Philips discovered that Sony and others were coming to the market with 16 bit Players Philips pushed/forced it's engineers into adding oversampling in the guise of a SAA7030 error correction chip. My reading indicates a Non Oversampling (NOS) mod which involves de-soldering & removing the SAA7030 chip and adding a 1k resistor to an isolated leg on another chip to provide 5v to enable 14 bit's to be read, the result is worth the effort.
I bought from Ebay a "Nos re-clock circuit mounted on a 20 pin a side plugin chip socket for TDA1540 SAA7030 based dacs and players" ie not just the NOS mod by just removing the SAA7030 chip and soldering in 4 wires this apparently re-clocks the TDA1540 chips (x2).I still have the replacement for the CD104 a John Westlake designed Cambridge CD4 se and he rates it as one of his best. It is the only CD player I had at that time ever heard/liked under £1500 this modded CD104 probably edges it.
I bought a pristine CD104 off eBay, this CD104 even arrived in it's original cardboard box sold as defective ie not reading CD's. Having already modded my original Philips CD104 running in his own system, with my latest purchase John jnr. took about an hour to drill & wire through the "griplets" dismount the SAA7030 soldering in a 24 pin chip socket then plugging in the "non oversampling/re-clock circuit" off eBay. then reassembled.
Both of these CD 104's are still working beautifully, I now use the CD4 se as a transport with a DAC I bought last year, not necessarily better just a different presentation.
Unfortunately most of the pictures went when Photobucket started charging.

@Mike P thinks Silmics are better. Sigh
