I suppose you can guess what was my weekend entertainment. The last 33R was finished measurement at 3:30am Sunday PST

What are in the bag?
Before I forget, I better describe what are in the bags
For those who purchase 2 sets:  there is one large bag for each person, the person's diyaudio id is on it.  inside the large bag, there are a few smaller bags: * One is labeled Assorted which contains 4 matched 220R's, 20 x 1K, 8 x 47R, 8 x 1.5K, 4 x 100K, 2 x 10R. Same values are wrapped together. * 3 bags labeled 33.X, each bag contains one set of 8 matched 33R resisters. You will be using 1 from each bag and parallel 3 of them for each 11R location in the schematic. * 4 bags labeled 220.X, each bag contains one set of 8 matched 220R feedback resisters. You will be using 1 from each bag and parallel 4 of them for each 55R location in the schematic. For those who purchase 4 and 5 sets:  there is 2 large bags for each person, the person's diyaudio id is on it.  inside one large bag, there are a few smaller bags that contain the must be matched resistors: * 3 bags labeled 33.X, each bag contains one set of 16 or 20 matched 33R resisters. You will be using 1 from each bag and parallel 3 of them for each 11R location in the schematic. * 4 bags labeled 220.X, each bag contains one set of 16 or 20 matched 220R feedback resisters. You will be using 1 from each bag and parallel 4 of them for each 55R location in the schematic. Nic, your 220R's are in bag of 12 and bag of 8 as I was too lazy to rebag them, but they are totally matched.  inside the second large bag, there are: * 1 assorted bag that contains 8 or 10 matched 220R's, 4 or 5 x 10R's, 8 or 10 x 100K's. Same types are wrapped except the 220's. * 1 bag of 16 or 20 x 1.5K * 1 bag of 16 or 20 x 47R * 1 bag of 40 or 50 x 1K DO NOT pay too much attention to the .X value. This is just the reading from my Fluke. I am pretty sure it is not 100% accurate All it matters is the same readings to designate as matched. Thanks!!

For those who are in the PRP/Fuku GB AND are also in my other 2 GB's and are not in USA:
 2SK3897/2SJ618, Keratherm Pads, see this spreadsheet.  2SK2013/2SJ313, see this spreadsheet. You are qualified to ship these items along with the PRP and Fuku. I sent some PM's in the last few days to remind this option but didn't get all response. I am gong to finish up match the 2SK2013/2SJ313 this weekend and will calculate the total of your batch and request payment. I can accommodate however you want to ship your items, but please let me know. I will great appreciate if you tell me your shipping preference (direct or with PRP/Fuku). Either spreadsheet has my email address next to my id. You can email me using that email address (my PM inbox is quite full). Thanks!!

Fred,
I missed the Keratherm Pads GB. Is this closed now? Cheers John

Hi John,
I ordered 34 extra T02474 and a lot of TO220. Let me know how many do you want, and I will add to the spreadsheet. Thanks!!

Many thanks Fred,
Just to double check is this quantity sufficient for a balanced F5X? I assume 12 x TO2472 and 28 x TO2204 going from the spreadsheet. Cheers John Last edited by johnwmclean; 29th October 2011 at 06:48 AM.

For each channel F5X, you need 4x Keratherm Red TO2472 for the main amp 2x Keratherm Red TO2472 for the regulator 8 X Keratherm Red TO2204 for the rectifier diodes If I am not totally forgetful (I am occasionally these days) that's all you need. Patrick

I think you meant :
12 X Keratherm Red TO2472. 16 X Keratherm Red TO2204. And I would suggest you order 25% extra, as they are fragile. You might have to replace them if you for some reason have to unscrew your devices from the heatsinks. (i.e. only good for one time if you are unlucky) Patrick
