Yes, this may be, but this is not due an incorrect RIAA, so to say the incorrect RIAA did not prevent the amplifier from sounding good

Dear Docali,

You remember earlier that I mentioned that I had sent and email to Walter electronics in Germany about the power supply for the SRPP preamp.

Well guess what, I have only just got a reply from a heir Wildtraut only now to advise that it is too expensive and difficult for them to send their products to Hong Kong????? How is that for service? This is the worst excuse that I have ever heard in my entire life.

I have stuff sent from Europe sent through the post all the time, all the vendors do is charge for the additional airmail postage and send off the parcel through the post office.

It would have been better for heir Wildtraut to just say that they are not interested in doing business.

I must say that I'm not at all impressed!!! Never mind, I will go to other more willing vendors who always welcome business. Is this the new style of doing business and customer service provision in Germany now?

Anyway, just a rant.

Regards,

Steve

Hi Steve,

this is disappointing, indeed! But, on the other hand it is quite easy to the HV part for yourself using TL783 as described in the original paper.

Dear Docali,

I am now finalizing the power supply boards for the SRPP. Have no choosen a transformer yet, any suggestions?

Also what tubes have you used with your SRPP? I am thinking of the Sovtek 12AX7LPS matched pairs which have a Long Plate - Spiral and are supposed to be copies of Siemens.

Have no thoughts yet on the 12AU7 and the 12AT7, any recommendations on the best combinations? My preference for music is Jazz and Classical.

Regards,

Steve

Docali,

The link with the SRPP Circuit appears to be down? Any reason? I just wanted to visit to download the PCB layouts but failed?

The link address again is: -
