SURFING MUSIC SOUND-WAVES

Just a short note, that with limited budget too , you can have a  line-amplifier with superior sound.

I happened to work together on this project with my close Singaporean friend Chan - stationed here in Jakarta  ;  he builded his own superior wooden chassis, while I sourced and try build the other ends , all  based on very limited available budget. The result is staggeringly superior  beyond my expectation !

We did not go for exotics,  the only part we indulged were the paper-in-oil coupling capacitors, and mind you - their price  are a very  fraction of the expensive Auricaps , Audionotes or Jensens audiophile caps .

The schematic used is a simple one stage SRPP with the  12SN7 tubes, which will give Chan the flexibility to play with the 6SN7 ( 6 volts versions) in the future.  A headphone connection is added to accept his Sennheiser 600 Ohm input load.

So , why  continue dream of the famous  Aikido with its 4 tubes ? . A simple KIS (keep It Simple) based line-amp will give  superior sound too !!

 Technical specs :

Tubes : one Phillips AZ1 solid plate, two RCA 12SN7. SRPP , Plate voltage 258Vdc , auto biased.

 Cost ?   Rpa 2.500.000,- (equivalent US$250.- for all )

Here is the process in a nutshell :

This is another poison version  I tried out  on  Chan's line-amp - my  vintage Valvo AZ1 meshplate rectifier tube
