Default DX Power supply query

Hi Carlos

I like the look of your amp and have a question about the power supply for the amp - Greg's site: (from DX PSU schematic:- Greg's Web Site).

I've always believed (rightly or wrongly!) that the power supply is the heart of an amp and I always like to upgrade the components where possible.

I will use Mundorf capacitors for the large filter caps but is it also worth upgrading the resistors and caps (R1 to R6 and C1 to C4 & C9 to C10) with fancier components. What do you think?

Thanks

Default This is a good idea...if you believe they can result in better sonics

then go ahead because you may perceive such kind of differences.

Our belief is what we need to feel good and feel happy.... i have a friend, a girl, that is awfull alike a bus crash against a wall...but she does not think she is ugly...she is happy as a hell the way she looks.... so...what is real and what is not real does not matter..what matters is what we think, what we feel and what we sense.

regards,

Carlos

Default There are people asking for TO3 option to this amplifier

Many guys, mainly in Brasil, wants that.

Also dear Evette have asked...he can provide boards too if he wants.

So, Juan will produce a pcboard having TO3.

Carlos

Green boards from the Brazilian group buy.

Hello guys for those who like TO-3 transistor type I'm working on a new Dx Blame ST layout and I'm trying to make it as elegant as possible, the goals is to have a great design but with a nice vintage look and classic look, I have been checking older models from 1970 to 1980 amplifiers style layout I'm combining this layout styles with today's must common available parts as possible, I know must people will say Dx Blame ST is been done long time ago, I say good stuff does not age is the people thoughts that ages, Carlos help me a lot in many many way so the best I can do is keep he's designs alive for many years to come, I'm not an expert but doing this make me feel great and I love what I'm doing, not for money, nor get famous I'm just a simple guy that like audio amplifiers so here is the layout is not done yet until I'm completly sure all is 100% correct the board is about 160 mm by 108 mm I might be able to compress it a little bit more, this will take time, ok guys have a great day and keep a good work .


Regards
Juan

Locate the +ve Power IN and the -ve Power IN and the Power Ground next to each other and preferably next to the output devices.
