Group Buy: Mauro Penasa MyRef Rev C kit

[linuxguru]

This thread is for expression of interest in the Mauro Penasa MyRef Rev C monoblock kits discussed at various threads at diyAudio:

My "audiophile" LM3886 approach - diyAudio

The new "My Ref" Rev C thread - diyAudio

MyRefC build guide - diyAudio

I will be offering a kit (including the PCB and everything on the PCB) for Rs.1500 each. These are monoblock kits, and you will need two to assemble a stereo amplifier. The kits will be supplied unassembled. In addition, you will need cabinet and chassis components, transformers, connectors, cabling, standoffs, heatsinks, bezels, switches, etc. of your own choice.

I will post the payment details in due course (most probably by PayPal and/or EFT).

Please indicate your interest by posting a follow-up with the number of kits required, and questions if any. You don't have to make payment now, and you can change the number of kits later.

Keith dosth,,

I wanted to see how the completely built unit looks like and what will be the final specification of a fully built unit. As I am a noob and have zero DIY skills I was kind of hoping if Siva can help build a unit for me ...

no eye rolling this time

Kittu.

For those who want to see how the boards look, here's the amp
I made from the MyRef group buy at DIYAudio last year.
The boards Siva is making are going to be a bit larger to accomodate
better parts and hence will look slightly different.

The amp is an amazing value for money.
Listening impressions - I am not too good with descriptions, but
it sounds excellent. Absolutely quiet and hum free, and a
very musical amp. Multiple group buys of this amp on diyaudio have
been extremely well subscribed to - which speaks of the high regard
for the quality of this amp.

This is a valid point. Most of up do not have DIY skills. But asking Siva may be taxing him. It is too early but we may seek one volunteer per city who has the will, ability & where withal to undertake the work on behalf of willing members for a fee. Also, we must also seek other components like transformer & chassis as group buy. Scouting for one or two pieces individually is not only unfruitful but also much more expensive.

 

[gautamz]

I'll be interested in picking up 2 kits to make a stereo amp.

Let me know about payment, etc.

 

[GeorgeO]

I have a friend here in Bangalore (PHilip Isaacs of Lizzner Electronics) who should be willing and able to assemble it, if needed.

 

[Hiten]

Some specification of this amp (Copy pasted from web)
* Passing band (typical-3db): 2Hz-70Khz
* The maximum power (8ohm): 40Wrms
* The maximum power (4ohm): 56Wrms
* Damping factor (8ohm): >200
* Relationship S/N (600ohm): >96 dB not weighed
* Typical THD (20Hz-20Khz, 1-40W 8ohm <0,05%

@ Gobble ~ Yes, this was too tempting to let go.
@ GeorgeO ~ Uptill now I see three people interested in complete build unit. Can you give rough estimate of it from your friend.

Interest in kit so far
Keith ~ 2 Stereo Kit
me ~ 1 Stereo Kit
gopib ~ 1 Stereo Kit
anilva ~ 1 Stereo Kit
gautamz ~ 1 Stereo Kit

 

[captrajesh]

In Chennai, we have Mathew Syriac, who has also become our member of our forum. He is young, enthusiastic and energetic and has the ability, will & where withal to undertake the projects. I'm sure he will undertake the work.

Hi Hiten,

I had expressed interest in the earlier thread and didn't think it was necessary to opt in again. Anyways, I'm interested in a pair for stereo application.
