Does anyone know where I can get transistors for a 30 yr old Spectral amp DMA200?
It sounds like VN are gone but PN are not gone yet. I guess the VN's could be replaced and pray that it will play. Larger heatsinks are being put in.

@holmz thanks. It looks like they have the VN but not PN.  
Improving Comcast modem signal
I have to reboot my modem once a week due to loss of internet signal. While streaming, I frequently get “network error” on my streamer and music breaks up. I can only assume that the internet supply is inconstant.

I will call Comcast to get their newest modem.

The one that I have has an internal power supply. Sksos, what grounding device are you using?

I hear a lot about the Ground loop issue. What is the problem it can cause and how can I deal with it?  
The Coherence system Add Powr Sorcer X4
@bemused ​​@glory  @Ozzy, who is also a fan of Sorcer X4 says the main benefits occur in lower frequencies. Do you find that to be the case in your systems?

Has anyone noticed a significant improvement with an LPS for the modem?

@mitch2 I tried Netgear modem with my Comcast system and I could not get my internet to work. So, I had to go back to the Comcast modem. May be the gigabyte capacity of Netgear conflicted with Comcast?

@fuzztone, Does Comcast have a range of modem quality?  
Power regeneration - good idea? PS audio?
I think it would be interesting to measure the distortion level at my home. Can anyone recommend a meter for this?    
Power regeneration - good idea? PS audio?
I talked to Torus and they say that noise <20kHZ is not filtered out. Regardless what the measurement says, I think the acid test is whether it sounds as good during the day as during the night.  
Power regeneration - good idea? PS audio?
@atmasphere I have Torus RM20 power conditioner, but I am not sure if P20 will lead to actual SQ improvement. I still hear a significant improvement in SQ late in the evening (with RM20). I am looking for conditioner/regenerator that will improve ...

@atmasphere , do you use P20 for your system? If so, do you plug in your preamp and amp into the same P20? Some people use separate power conditioners for the amp vs the rest.   thanks, Jay
