Mastersound Compact 845 with Pvsane 845T

Hi Patal, let us know how you get on because I too have a Compact 845 from Jordan, so will be very interest in the outcome

Jonathan.

Hi Jonathan,
Will do .The amp is curremtly back in Scotland with Jordan for repair and I have asked the dealer to ask his tech over there for his opinion in regard to modifying the resister.This was asked prior to recieving the excelent e mail from Phil.Mastersound are still of the opinion that the modification is required.However they cant offer much more advice as they insist on seeing the 845T valve to test/check it.
The general feedback seems to favour the 845B.
Regardless will gladly let you know the outcome.
Regards
Alan (Patal)

Hi Jonathan ,
The amp is now back and running with the 845Ts and sounds great.The tech thoroughly checked it out and put it on test for over a day with the 845Ts and advised it ran fine with no problems.Have not tried the 845Bs but the 845Ts sound fantastic and they are nowhere near burned in.
I also bought a DAC from a company called Black Lion in Chicago called the Sparrow (White)this lifted the system to new frontiers totally.More than pleased.
Kind Regards
Patal

Hi Patal,
Glad you like the amp more now with the Pvsane T's. Did the tech need to mod the amp in anyway or did the tubes just drop in and need re-biasing?? I have some Psvane T's here now but haven't tried them yet. Still lovin' the 845A's at mo. If the T's are better then it will be seriously good,
Thanks for getting back to me,

Jonathan

Hi Jonathan,
He put in on test for over a day and done the required measurements and said there was no problem whatsoever.He did say there was a significant re biasing but there was still plenty of room up or down to spare. Re 845 Ts they sound very good still burning in, indicators say they can take 70 Hrs so using Isoteck burn in disc to help the process.
Hope this helps
Patal
