@testrun This thread is about the PH9.0, which typically doesn't have a tube rectified power supply. That said, the older SWP 9.0 did and rolling that tube led to substantial upgrades! Did you have a PH9.0 with a tube rectified power supply? I asked Dan about that years ago and he mentioned the SS and tube versions were not interchangable.

@blisshifi Good Info about the 6C45. I thought the Sovtek was the only one. Thanks! |
I have been fortunate to have been demonstrated in the UK a Modwright PH 9.0 'SE' and not the 'X' Model. This attached is the sale add for the Phonostage I was demonstrated. _____________________________________________________________ Modwright Instruments SWP 9.0se Phono stage for Sale _____________________________________________________________ There has been a few years past now, but do recall it had a very warm sonic, that was very relaxing and I felt perfect for adding a colour to Chicago Blues Recordings. I am not aware if the 'X' Model is with the same sonic traits. If there is a Bloom with the 'X' model, and a it is wanted to be heard with a leaner sonic trait. My experience of the Amperex Bugle Boy's - 'Orange Text' has shown these are quite un-valve like when compared alongside a range of valves. What is good to know is that there are tube options to produce a Warm Bloated Sound, and the Antithesis of this being quite lean. I use Early 60's E88CC's in two devices. The choices made following quite a few periods of Tube Rolling, are Siemens and Halske in a Phonostage and Mullards in a DAC. Is it not strange that different Valves are selected from each other for different circuits? Tube Rolling does deliver a few curve balls.

Hey @pindac - the unit you were able to demo was the SWP 9.0 SE, not the PH9.0. The PH9.0 was the SWP’s successor about 3-4 years ago and is completely different design (circuitry, tubes, chassis) than the SWP. The SWP was very good as it was, as I owned it prior to the PH9.0. But the PH9.0’s noise levels and openness drove it to be an even higher performer. The PH9.0X was an even further upgrade than the PH9.0 by removing all caps in the signal path and instead using high quality Lundahl transformers that brought the fidelity very close to the $8K Modwright PH150. I did find the PH9.0X upgrade worth the extra funds, for anyone who is interested. I’ve brought this up in other threads on this forum which can be found if people search for Modwright PH9.0. |
