Topic: DIY Tube Amp and Tube Pre-amp? Who's Interested? (with Pictures)

[reynold]

First of all, to the moderators...
   - i've started this thread under "Service" board 'til i realized that this topic should be placed here in "Tubes" board, so i'm so sorry for my double post. Please delete my other post under "Service" board if needed. Thanks


Good Day PinoyDVD members

I have a cousin who's into Tube Amp and Tube Pre-Amp DIY for i think 7 years or more now and won alot of awards in some Audio shootout contest. And me as one of his client was impressed by his job especially with the Sound quality of most of his projects (Tube Amps). You can also ask Mr. Edrel Sison, our beloved co-member here in PinoyDvd about my cousin's credibility in Tube Amps DIY-ing, i believe Edrel is a Kumpare of my cousin

So if you would like to try or experience my cousin's work of art, you may contact him at 0918-4520558 - his name is Mr. Ruel Felix. You wont be dissappointed by his work

To Sir Edrel Sison, i hope you dont mind, for mentioning your name in this post, i just want to help my cousin and introduce him and his work here in our community. Thanks

To our Mods and readers of this post,
The reason why i posted this is that, my cousin is not really a computer geek, he really don't know how to use computers kaya di sya makapag-member sa Wiredstate and PinoyDVD or other Audio sites. I'm just helping him to be known in our community, nakakapanghinayang kasi ang talent nya. I hope we can support someone like him

Two thumbs up on your great work with tube amps, one can definitely say that you are indeed a veteran in this field.  Unlike others who pretend to be masters or even called gurus (but miserably fail to show even the trace of making a decent tube amp), you stand out among the rest, keep up the good work

[reynold]

Right now, these are the amps that have their prices, and ready to be ordered/made:

RF-1 Pre-amp                                                    - 8.5K
RF-C2 Marantz Design                                     - 13K
RF-AR Audio Research SP3 Design                - 17K
RF-P3 Conrad Johnson Premier 3 Design     - 16K


* For some technical details and other info, please contact Ruel Felix.
* as for the other amps in the pictures above or tube amps you have in mind, you may ask for a quotation directly from Ruel and you can discuss every details as well


Note: These clone tube amps was tested side by side with the originals, the result... Clones sounded better than the originals


Thanks,
reynold

Hi Doc,

It's better to directly ask Ruel for the price of amp/s that you want him to to do for you. Para ma-negotiate nyo na rin, i'm sure he'll give you a very reasonable price, madaling kausap yun

thanks,
reynold

[JAQY888]

Wow, galing naman. Thanks for sharing, bro. Reynold.
With your help, malamang dadami ang orders sa inyong cousin

I have an AV200 for a year and wants to convert it to tube output amplifier (DIY). Anybody there could help me get the schematics and part lists? I am new in radio electronics but can solder and knows a little bit of drawings and schematics. I would prefer an SET low watter design using the power supply and pre-amp of AV200.
Thanks
