content: I'm currently saving money for a good LCR-meter, so I want to get as much money as I can from this collection I got. What's the best way to flip these for some cash? Any ideas other than $1 a piece on eBay over 10 years?All ICs arenew, they are still sealed in the original anti-static bag they came in from the supplier. All original. (There are three exceptions, one set of 25 ICs are in an static-dissipative bag, one antistatic bag has been cut open (but untouched) and the 2SK557s are individually packaged in static dissipative bags).I hope someone here can appreciate them!Model/make; descr.; qtyHEF-4073BP Philips; Tripple 3-Input AND gate; 754538BCN Fairchild; Dual Retriggerable precision monostable multivibrator; 25N82S09N Signetic; Static RAM - On-Chip Addr Decoding 64 Word x9 bit; 20HEF-4016BE Texas; Quad Bilateral Digital or Analog Switch (4x1 Closer); 100EP-910PC-30 Altera; 40-dip; 5HEF4013BP Philips; Dual D-Flip-Flop with Complementary Outputs With Preset and Clear; 2574LS390 National; Dual Asynchronous Decimal Up Counter with Separate Divider 2:1 and 5:1; 2574AC244PC Fairchild; Octal Bus Line Driver, non inverting; 12HEF4069BP Fairchild; Hex inverter; 50AM27S41ACP AMD; Bipolar OTP Prom 4Kx4Bit; 36HEF4027BP Philips; Dual J-K Flip-Flop; 100HEF4001BP Philips; Quad 2-Input NOR Gate; 125HCF-4071 Toshiba; Quad 2-Input OR Gate; 25HEF-4081BP Philips; Dual 4-Input AND Gate; 50HEF-4071BP Philips; Quad 2-Input OR Gate; 50HEF-4011BP Philips; Quad 2-Input NAND gate; 75TC-4049BP Toshiba; Hex Inverter / Buffer; 29HEF4073BP Philips; Triple 3-Input AND Gate; 100HEF4081 Philips; Dual 4-Input AND Gate; 50HA-13157 Hitachi; 33W 4-channel BTL Power IC; 1TDA-1675A ST; TV-VA System, VA-E, Pin 11 = Input +, ESD-Protected 15-Sql; 1TDA-7394 ST; 2XNF-E, 28V, 4.5A, 2x28W (14.4V/2 Ohm, BLT); 1TDA-7385V ST; 4XNF-E, 28V, 3.5A, 4x22W Car Radio Amplifier; 1TA-8216H Toshiba; TV Dual Audio-Out, 40V, 3A, 2x13W (28V/8 Ohm) 12-Sql; 1TA-8215H Toshiba; Dual Audio-Out, 25V, 9A, 2x18W (14.4V/4 Ohm) 17-Sql; 2TDA-7560V ST; 4x45W Quad Bridge: Car Radio Amplifier; 1TDA-7377V ST; 2x30W Dual/Quad Amplifier For Car Radio; 1TA-8225H Toshiba; Audio-Out, 25V, 9A, 45W (14.4V/2 Ohm BLT) 17Qilp; 2TDA-7386V ST; 4XNF-E, 28V, 4.5A, 4x40W (13.7V, 4 Ohm, BLT); 1TDA-7365 ST; 2XNF-E, 28V, 3A, 2x6W (14.4V/4 Ohm); 1TDA-8568Q Philips; Quad Audio-Out 4x25W BTL 17-Qilp; 1TA-8210AH Toshiba; Dual Audio-in/Out 25V, 9A, 2x19W (13.2V/4 Ohm) 17Qilp; 1TA-8207K Toshiba; Dual Audio-Out 20V, 2.5A, 2x4.6W (12V/4 Ohm) 12-Sil; 12SK557 Hitachi; N-Channel MOSFET; 10

My best guess is that they were supplied by RS Components. I don't know what they are worth, which is why I'm asking in here.

content: The OTP, PROMs and Amps are probably worth something as a spares bundle to someone that repairs older gear as a side business. The generic semi's & logic aren't that special - probably include them as a freebie.One thing to keep in mind is that while they are new, you can only 'hope' they are in 'as-new working' condition...So a best guess of 25% of the new price would be fair - that may be around $150-200 plus postage for everything.My guess of their 'value' to someone that needs these specific parts.As a hobbyist's online grab bag - maybe $100 for everything.

content: could be interresting to have these for playing with the logic chips, last time I touched one I guess was between 87-89 when I was in electronics school, but I wouldn't pay more than 400-500NOK for them.

content: It's hard to make money from small items on ebay - there are so many charges to add on, and the far east suppliers can do postage practically for free.List a few of the more interesting parts to find out what you can make before you go for the whole lot. You may find it isn't worth the bother.
