Best psu for T-amps

[Nuuk]

BTW I'm not sure which I prefer between the 12v 7aH battery or the LM338

I'll be trying an SLA battery as soon as it is charged Leo!

The thing is that for example listening to movies I have to have the volume pot at about 3/4 volume, is this right with a 10k pot

If it's loud enough for you Phil then it's OK. The idea is that the gain of the system should allow you to use as much of the pot/attenuator range as possible, giving you greater control. Of course, some like to have max volume with the volume control advanced only a little as that gives them the impression that they have a (more) powerful system!

If you can't go loud enough with the pot at full volume, then is the time to increase the gain.

Be very interested in what you do to your t-amps, let us know how you get on.

I'm very much playing follow-my-leader with the T-Amp!

Well lets hope some more post their results

Regarding the battery I started using a pair of 10,000uf Siemans sikoral which seemed good enough, I tried the snubber on the end of the caps but to be honest I feel it does not suit this set-up too well, the sound certainly changed but something was not right, strange because it worked great with the GC's try it Nick and let us know what you think.

Reading other posts it seems the input stage is the biggest flaw with the SI T-amps, removing the inductor and replacing the low value ceramic coupling cap with around 2.2uf polypropylene is supposed to make a huge difference.
Also alot seem to say an active pre improves the T-amps alot, most seem to use tube pre's

BTW did the cheque arrive ok NUUK?

BTW did the cheque arrive ok NUUK?

That's what I meant when I said

PS. Leo, you and your cat will soon have a chance to see if I am right!

Try looking in this thread.

Thanks Roger

I've just fitted a pair of used spare 680uf BG NX caps on the pcb for the decoupling temporary until the 330uf Rubycon ZA's arrive (they are on back order).
Bloody things was a tight fit but sound a lot better than the supplied caps
