Just thought that I should post a summary of where I have got to in case anyone else gives the conversion ago.

Hi Danilo,
Struggling to find any 10UH toroidal inductors to fit in the Lepai. I was very kindly sent some by Alan but I need to go for a bigger case to fit them in (perhaps the next bit of my...
Hi Danilo,
I was very lucky as the Lepai that I bought for £18.99 a few years back has a genuine TA2020 in it. You can still buy the chip from a European distributor for about £9.00, well until...
Just thought that I should post how far I have now got with the Lepai Power Amp project. 2.2uf Input decoupling caps now in place and .47uf output caps - Vishay MKT1822 caps on the output. Tidied the...
Thanks Alan, I will leave the 2.2uf film caps that I put in it.
Regards Chris
Price reduced to £75.00 inc UK postage just to see if anyone is tempted.

Not sure about the Lepai's power amp input being affected in this way as the Beresford DAC Pre-amp out works well with a range of different power amps.
Anyone else?
Hi Andrew, You didn't although I was a bit confused by the reply.
The datasheet for the TA2020 does not go into this sort of detail.
I am looking at the signal decoupling and am aware that...
Thanks for this but I don't have any issue removing the preamp stage from the Lepai and the bypass works a treat (the mod is well documented elsewhere). I was actually asking a more specific question...
Can anyone help with a quick query please.
I have a 10uF cap on the output of my Beresford Caiman that I use as a pre-amp and just wondered if I need another cap on the input of the Lepai power...
Anyone need a rather nice 5v linear power supply for their Touch kindly made for me a few years ago by a fellow AoS member UV101. It includes all cables and UK postage. I have posted a few pictures...
Just updated my list just in case anyone can help out.
Best regards

Hi Alan,
Thanks for having a look for me.
Wanting to use them on my Lepai TA2020 power amp project posted in the drawing board. The stock ones look a little suspect and not sure if they are to...
Anyone want to sell on a few capacitors?
I am after the following for decoupling duties:
2 No. Vishay MKP1837 0.01uf capacitors.
Also looking for 4 No. toroidal coil wrapped inductors 10uh...
Considering that the amp was around £20.00 and usually collecting dust on a shelf well worth ago. If you only want a power amp the first mod - op-amp bypass mod gives the biggest improvement and very...
Ok not much interest but here goes.
Next mod done last night and tested.
Taken out pot, tone switch and tone controls - quite tricky and need to go slowly. Make sure that the tiny casing earth...
Fairly easy to do.
All I did was remove the surface mounted resistors at C30 and C31.
Remove the bipolar capacitors at C20 and C21 - carefully as I reused them below.
Add flying bypass cables...
Just wondered if anyone is interested in posting modifications to the newer style Lepai amp? Lots of postings over on DIY Audio for the older red board ones but not so much on the newer style PCB...
Amp now Sold.
Thanks Gary and please let me know how you go on.

Amp still for sale and I will include the UK postage cost. Just to be clear this is a Avondale made A260 amp and not a self build one. This was produced by Avondale before the M130 mono blocs which...
Amp still for sale if I can tempt anyone?

So far so good and really like the sound changes that the low cost poly caps have brought. Much cleaner sound than the elcaps that were in previously.
Looking at the ceramic resistor - 5w 3.9 ohms...
Noticed an old thread about trying cheap Maplins super tweeters and wondered if anyone has had good results retrofitting them onto speakers to add a little "air" to the sound. I noticed that some...
Thanks to everyone for the advise and encouragement.
I have taken the xovers out of the cabinet and looking for a couple of small boxes to mount them into. Used a bit of spare Avondale black link...
Hi Martin,
Hope that those "new speakers" have been keeping you up at night!
Got a couple of cheap Wharfedales that I am tinkering with (film caps etc on xovers) but need a little pair of stand...
