Welcome to the Carver Site!! Nice collection of Phase Linear gear!!

@JayBee Welcome to the Carver Site!! Downloading the service manual shown in our database will get you a schematic of the 6cb. Its shown on two individual pages. It doesn't look like any information is missing from each of the pages. If you wish a continuous scan of the schematic you can download the very same manual from either of these two sites. https://www.scribd.com/document/723336078/Carver-Tfm-6c-Sm This one should download automatically https://audiocircuit.dk/downloads/carver/Carver-TFM6C-pwr-sm.pdf Or if you prefer to look over the Carver list on their site use this link below. They contain just about the same information that is available here. https://audiocircuit.dk/carver/ And a host of other manufacturers information here, https://audiocircuit.dk/download/#google_vignette Good luck resurrecting the TFM-6CB. For Hsv, I get Huntsville International Airport in Alabama (HSV)? Thus Huntsville Alabama area.

Just about anything can be going on. I assume you have alot of confidence in the repair facility. Have you contacted them for some guidance and or suggestions? I would do one of two things. Work my way backwards removing a component and testing to see if the hum or hissing has gone away. Or unhook everything then add an item one at a time. This is in no particular order, so..... I remember from your previous post you were trying to bi- amp some speakers and at the end you had everything "singing". So things worked then. Something has changed from then to now, is anything new? 1. I would plug the bluos into the CD input and then test. 2. Next I would remove the sub from the bluos then test. 3. I assume the same speakers. What make and model? 4. Was the new non inverting amp tested before and worked fine so we can rule it out for now? Still bi-amping? 5. Tubes were replaced. Who sourced the tubes? What were they? Matched sets and tested? Line board and or phono board tubes? 6. Any other parts replaced on the preamp 7. Any new cables? Just look at one thing at a time and something will pop up.

Welcome to the Carver site!! Should be an interesting pairing. I use a 6cb in one of my systems. What's the candidate for the preamp? As for the music side, records or cd's?

If you don't see what you need in the Manuals and Specsheets section, maybe one of these three offerings on eBay might be of interest. https://www.ebay.com/sch/i.html?_nkw=carver+klw+audio+service+manual&_sacat=293&_from=R40&_trksid=m570.l1313&_odkw=carver+klw+service+manual&_osacat=293

Welcome to the Carver site!!

Welcome to the Carver Site!! Tell us a little bit more about the system using the PM175.

@MattB @gwolford A few places I have in my saved folder, Listed in no particular order https://lptunes.com/collections/vpi-turntable-belts https://www.lpgear.com/category/V1.html https://www.turntableneedles.com/Rubber_Drive_Belts-Tape_Decks_Turntables Was able to source a tt belt from Amazon based on knowing the size and cross section information. For mine I used this to start the search; Turntable Belt for Record Player 20.7" Replacement Flat Medium

Welcome back!!

Welcome to the Carver site!!

Welcome to the Carver Site!! Tell us more about yourself and your equipment. Download the file in this link to find belt size information. And for good measure look at this

Welcome to the Carver site!! I previously owned a IV. Question, Is the unit still operational and not experiencing any problems, and you just want to get it refreshed due to age? Or it is experiencing problems? At one time I owned a IV and it gave me many years of GREAT pleasure. I had a recap done and the unit completely went dead after one year. Nothing related to the recap just the processor failure it was determined. I really loved the unit but not enough to try fixing it again nor purchase another replacement. I put that money into a new Marantz AV unit that had a 5 year warranty. Its not exactly the same, but I have improved several items around it that more than makes up for the loss of the Sunfire. I also was able to incorporate all my older Carver equipment and add new modern day equipment so it was, for me, a big plus.

Welcome to the Carver site!!

Welcome to the Carver site!! Tell us what's in your collection.

I will also go along with @Sk1Bum for the C-4000t because of the addition of the Digital Time Lens function.

I would go with this preamp, Its a Carver C-4000, it looks smart and classic old school. It is available here, last one in the list, https://soundsclassic.com/preamps.html Next one after that would possibly be either a c-1, c-11 or c-16 Tuners as suggested by @Sk1Bum

take a very close look and I mean a very close look at the RCA connection points for the tape input and output and for the pre outs for the front. For me they look broken as the outer shell is missing.

Are the pictures that you posted are they of the unit you are thinking of purchasing?

They are different because what is shown is a CT-26v. What I show is a picture that represents the model you mentioned in your post, a CT-23.

@Scott Andrew On the back of the 23 you use the audio out to go to the input of the amp.

Welcome to the Carver Site!! Looks like the CT-23 is a nice fit for your two-channel setup. Make sure that it has the remote. If you are thinking of a system beyond a two-channel, say a surround sound configuration then maybe something like the CT-26V or the CT-29v (with the remotes) will be good to start off with. With those two units you can add amps for a center channel, surround and a sub as your system grows. For your 420 amp, you will need to get or make an interconnect cable that goes from an RCA to 1/4" phone jack. The 420s were sold in a US configuration and an export configuration and either configuration accepts balanced and unbalanced inputs. The manual covers this. Again Welcome.

Welcome to the Carver site!! @TomSens 6 likes and advanced to Novice!!, you are now able to upload some pics in a topic of your system(s) in the Members Systems area.

@Ultramafic1 That will be a fantastic build on the amp and a great combination with the C-1 if I may say so. Why, my son has a PL 400 paired with a C-1 in his B system. I think you are going to like it.
