Hi, A few years ago, I disconnected the 24v feed to the gain/MPX cards and ran full voltage from NAPST into a pair of Teddyregs installed inside the NAT01 to power each channel of these cards at 28v. The improvement was not subtle. HTH, Pete

Hi mattgbell, I have been using a DEQX for many years and can assure you that they are a wonderful product. The only thing is that you really need to know how to read frequency plots. The software is unfortunately, very user unfriendly so you really do need someone that can set it up for you. I...

Thanks for that; I thought that those things on the side of my head were for cooling:D The reason I ask is that it is a real hassle removing my Linn from its head height wall mounted rack, and I can't do any alignment etc when it's in there. I'm just trying to get some opinion whether it would...

Hi JoeP, thanks for the response. I have only just found the Supex in its little box. The Karma rides nicely and not too low. I'm just wondering whether its worth the effort of changing them around, that's all. One question though; why would the suspension be affected when neither of them have...

I have an old Linn from the late eighties with Ittok/Karma, which hasn't had all that much use but has beckoned since making Neil's excellent mini phono board with NJ 323's. The other day I unearthed a virtually new Supex 900 which had done very little work on a Rega 3, almost 20 years ago...

I'm still fighting this thing. All of the troubleshooting tests have been done a couple of times and everything checks out. I have replaced Q1 to Q10, removed and checked C4,5,6,7,10,11 (C9 linked), soldered a .1uF cap across R14, split power rail and added OR15 to each Mosfet instead of one...

Hi Kit, of course I never thought of that. Would you kindly put me on the list please? In the meantime I'll look for small alligator clips. Is there anyone else here in Aus on the program? Regards, Pete

I'll give you, "old bas@#&d", you silly old fart!!! After speaking to you tonight I will be really interested in comparing your spare 42.5 with Kit's cards against my modified 32.5. I would also love to run the cards in mine but, seeing as my boards are powered separately from the main board...

OK, I have now changed Q9, Q10 and when nothing changed I then changed Q1, Q2 for still no change.:confused: Another interesting thing is that not one component on the -ve rail, which is .5V higher, is any warmer than any other. Unfortunately I don't have BC556C's here so will need to get some...

[/COLOR] Hi PD, here are the measurements you asked for. Regards, Pete

Thanks PD, voltages in red. Pete

Hi PD, I measured putting a signal in and the AC is definitely larger than DC. I just happened across my photobucket password so here is the schematic; http://s873.photobucket.com/user/selby2/media/GB150Dupdatedschema_zps5639f18f.jpg.html?sort=3&o=0 Previously, according to Greg's...

Thanks PD. I'll give that a try. Pete

Thanks PD, the only problem is that I don't have one and the only person I know with one is overseas. Wouldn't the module run hotter than the other one if it was oscillating? BTW, I forgot to mention that DC offset is also on par with the other channel. I did note last night that the...

Greg has been helpful as usual but doesn't seem to have any answers to this one. Thanks, Pete
