Hello,
Have the following for sale.
A variety of chips including receiver, filter and a a DAC chip. All genuine ICs.
Avel Lindberg toriodal transformers. These are fully encased and unusually sheilded between the primary and secondary etc. Toriodals are wideband devices so this is important in DACs and pre amps etc (the screening between primary and secondary (properly designed)).
Also a host of LT1086 and LT1033 three terminal regulators. The Vero board is quite good quality also if you have a scalpel as you could make the circuit on it. Will include more photo's and schematics of what I had in mind originally.
Think I just bought a non oversampling Audionote DAC with valve outputs at the time and never bothered pursuing it.
Anyone interested ?

Hello,
Just updating the info. on the above post.
1x Burr Brown PCM63P-K Japan
1x Crystal Semi CS8412-CP
1x NPC SM5842AP
1x NPC SM5843AP
All these are in DIL24 packages and never been used. They all genuine parts.
4x LT1033 adj. 3 term regulators TO-220 Package
4x LT1085 adj. 3 term regulators TO-220 Package
Again never used.
1x Avel Lindberg Toriodal Type 40/3693 0-15v 0-15v 10 va per winding
Has 5 pins on other side for 120v and 240v operation and pin 5 is the screen.
1x Avel Lindberg Toriodal Type 40/4298 0-9v 0-9v 5va per winding
Has 5 pins on other side for 120v and 240v operstaion and pin 5 is the screen.
Pin 2-3 is connected together for 240 or 220v operation. Secondarys can also be connected in series and parallel.
Again never used.
Can throw in a variety of Sanyo OSCONs also. Got more than in the photo etc. I did have three more PCM63P-Ks and a PMD100 etc but sold these years ago. I think I was going to try a balanced configuration with PCM63P-Ks
Should have some 7404 ICs around also.
Have attached two schematics of the DACs designs I had in mind.

Hello,
Thanks for your interest. Your best to ask in the digital forums about this.
Are you trying to do non-oversampling and such like ? The big thing is too use I2S or PDIF/SDIF etc and eliminate all the signals going on the same data link.
Interestingly, Naim Audio came to the view decades ago, that there is no advantage of having an off board DAC per se (esp. using SPDIF etc) and dismissed this arrangement and they were right!
PS. Another problem selling to the US/Canada is the cost of delivery can exceed the parts of course!. I remember selling genuine Mullard GZ-37 rectifier tubes to someone in the states, and it took three weeks for delivery. As I said to the buyer at the time, if I had used someone like Fed Ex/UPS from the U.K. it would probably cost more for delivery than what I was selling the tubes for!!

Hello
I would try both OS and NOS for my TDA1541A, I have a SAA7220 digital filter but this digital filter do have a bad reputation.

Hello,
Am still selling these parts with the exception of the digital ICs - these were sold to diyaudio user anders "secanbj" and he seemed happy....EU sales are no problems and I take paypal etc.
PS. I could probably throw in some other stuff (if you request it - boxes of stuff here! 🙂 that should off, could off and would off been built apart from laziness on my behalf. Not strictly true was very busy at work etc.
Looking for 40 pounds for the lot including delivery. Will accept paypal.
PS. Just moved in a new place and starting to need money....no joke....
Let us know if interested,
Kevin
