Amplifier Destroyer par excellence
Hi David as these things go one of my Quads has developed an issue and needs to go back to Andrew Jones of Aquadthing to be serviced or repaired so will have to wait till that is all completed before I can get down to the issue at hand . I have six NOS Mazda PL509 valves and have been trying to get a further two of the same type so that I can do a full valve change . Not seeming able to find a further two except at very silly prices. Sourced some Brimar NOS and will see if using them with the Mazda will be okay . Once I get the complete sets of valves it will be back to Glenn as they will need biasing and my model does not have the external bias points that appeared on some models which make it easier . At least you are only a short drive from Glenn while not long in miles the last part of the journey after you leave the motorway is a bit of a drag . Lets hope that a complete new set of valves giving out the best it can do will work .
With regard to my set up it is a very strange one for lots of others. I only use a digital signal either from a CD transport (Theta Data Basic ) or a streamer/player (Rpi4 Allo Digione Signature) which feeds a digital output in to my MiniDSP DDRC 22 D which then adds DIRAC Live DSP and feeds the treated digital signal to an Arcam D33 DAC which powers the Croft OTL 3 Direct . All of the volume control is in the DDRC 22D in the digital domain .
