Yes I meant the NTE725. I would like to upgrade this part. Not just replace it with a knockoff. PPL are you out there? I will have to look at the thread you posted later Budgie. That site is blocked here at work. Thanks for the reply. G

It can be replaced with a NET725 but I would rather upgrade the opamp not just replace it. The opamp goes in a driver board for a Harman Kardon citation 16. Any help is appreciated. Thanks. G

Anyone seen this? http://www.pmillett.addr.com/hybrid_head.htm G

I tried about a year ago to find some silmics with no luck. Does anyone know where to get them. It seems they are almost impossible to get unless you are willing to buy about a 1000 of them. G

Well obviously now that you've built it you have to take into apart and overbuild it. G

Anything is possible (almost). Start out with a simple Cmoy amp and go from there. There is ample information as well as a good tutorial on building the Cmoy. Look here: http://tangentsoft.net/audio/cmoy-tutorial/index.html Have fun! Gman

Check out this link: http://www.amveco.com/pc_mount_drawings.html#tech1 That should get you on the right track.

The original has some typos. Several capacitors have been changed on the advice of Rohit. Also he modeled the circuit using an IRF530 on the output stage and say's the results aren't bad. But as they say the proof is in the pudding(listening). G

Hi guys, I've been working on this circuit for a couple of days now and I think it's ready for comments (good or bad). This all started when I ran across this schematic: http://members.tripod.com/~gabevee/sstubepre.html I thought that the circuit would make a good headphone amp with a few...

OK. I'm going to give this a shot for you. First let's start with the Panasonic pot. Hold the pot with the shaft facing you. This will give you six pins from left to right. The right channel goes like this: The incoming right channel signal coming from the RCA jack connects to the sixth pin(I3)...

I've sent an order to Michael by email 4 times in the last week and have gotten no reply. Does anyone know if he's out of town or is he running that far behind? Thanks.

Thanks PPL. Have a good one.

PPL. I was planning on doing the same thing as Aeberbach except I was going to use a buffer to drive a pair of Grados off of the pre out from a NAD integrated amp. Do the BUF634 have enough umph to do the job using only one pair? Also is an input bias current of +_5uA acceptable for this...
