aaa 0 Report post Posted November 13, 2004 (edited) Everyone building an amp will need many parts. Most of the parts in anyshop are irrelavent to the need of an headamp. Why not keep a list so that the junior don't have to waste time on items the pioneers have already found. This list will be particular for PPA, but parts for most amps are more or less the same, it should be useful to ppl building other amps as well. Let me start the list C1 Nichicon Finegold 25v/33uF @ Koba, People's park centre 2nd floor The right size DxH 12.5x20 for offical PPA PCB in harmond casing C2, C4 Blue 2.2uF/50v polyester unknown brand @ Koba cheap cap that will fit in offical PCB C3 Wima MPS-? 68nF/63V @ Koba The right size WxD 2.5x7.5 for offical PCB R10, R11-14 1.43K�6¾8 1/4w, deep blue,unknow brand, good looking, need 4 hole width @Koba Although the offical value is 1K, but 1.43K is just as fine. 0.1% mean good quality. Q1, Q2, Q3 2N5484 and 2N5486 are available at Farnell. Federal component in SLT 2nd floor handle them @ $1 each TLE2426 available at Farnell. Federal component handle them @ $3.50 each Buf1 Intersil HA3-5002 available at Farnell. Federal component handle them @ $7+ each for q>10 Volume pot Koba currently (Oct 2005) have some stock of ALPS 27K series 50K stereo Log type potentialmeter. $15 each. please add on to the list by copy the list and then edit it.

bpribadi 0 Report post Posted November 13, 2004 How about the main component, the Op-Amp? OPA637 > Farnell ~ SGD 37.5 (after GST), don't know how much in Federal. AD8610, don't know where to get in Singapore, but I prefer the AD8065 over the AD8610. Neutrik Locking Socket > Hung Brothers & LHS ~ SGD 7.5 not glod plated, ~ SGD 11 gold plated.

skyskraper 0 Report post Posted December 6, 2004 (edited) ah i wish i spoke xnese! if anyone is buying a heap of the buffers let me know. i want to outfit my PPA with 6 of them, so the price for 10+ is a bit much for me! but $1 extra isnt too much. edit: perhaps we could do a group buy for some stuff like the alps pots from china? or if any of you guys are making a dynahi soon maybe we can group buy for transistors/pots?

huangyong 0 Report post Posted December 6, 2004 perhaps we could do a group buy for some stuff like the alps pots from china? or if any of you guys are making a dynahi soon maybe we can group buy for transistors/pots? What we need is a reliable person to coordinate in China. if only you can find one. dynahi. hahaha.. in Singapore, I dont even heard a person who makes a Gilmore Dynamic before. Because the parts is so rare. and it require high skills in DIY also.. those tedious job like transistors matching and stuff. and those massive heatsink.. it's all expensive stuff in Singapore. I think only our Chief DIYer in SGH: firefox can do it. Share this post Link to post Share on other sites
skyskraper 0 Report post Posted December 6, 2004 ah i thought u guys might know someone in china. i just bought some boards for a dynahi in the long future. transistor matching isnt too hard. im just worried about troubleshooting. its a hard circuit to work with by all accounts.
