I'm trying to post a photo of the signal routing, but it won't go. The image is 89K, but the board tells me it's too big - over 1meg. Hmmm....

Nice work Michael.

It looks like a lot of the main board could be eliminated if one were to use an off-board volume pot and off-board input caps.

Or - if bi-amping - the opamp etc. could be used on one amp as a low pass filter and on the other amp as a high pass filter.

Default Lepai lp222a vs Trends Audio TA-10

Hello

firstly thanks to all for the very interesting threads.

What I read is that ta2020 perform better the bass and is a little more powerful that ta2040, but ta2040, if well configured, can have good performances in low too and maybe in medium and high frequencies can perform a little better than ta2020.
Then performances depends a lot by the confirgurations.

Now a question: please somebody had the chance to compare Lepai lp222a (with a good transformer 12v or 13.8v stabilized, 3A) no mod with Trends Audio TA-10 no mod?
Feelings? Frequency response? Signal noise?

Thankyou very much!

rob

I am sorry. I wrote 2040 instead of 2024.

No contest. The Trends TA-10 is much better.

With some modifications the Lepai can sound almost as good as the TA-10. I run my Lepai on 15V 3A, so that gives it a little more headroom.

It's good to know where it stands amongst other T-Amps.

Hi Fin,

Sorry about that. I thought I had enabled everything but it was the setting Make e-mail address invisible that I got wrong. You should be able to see the button e-mail now.

Default Power Supply Mod for Fin

Hi Fin,
I mentioned that I got some NAN 40's for a retired techo friend.
I told him that I had blown a fuse on mine so he had a look at it and his judgement is that the diodes C10 11 12 and 13 are not suited here, so he replaced them with (Dick Smith part no.) 1N4007.
He's also drawn up a full schematic of the thing.
If I can ever learn to work this scanner I could drop you a copy. Let's know if you're interested.
Cheers
