Thank you for sharing, I thought would not learn much, however, I did. 😀 Speaking of RCA, I thought had lost a channel in a temporary solid state so far found no information on what to replace the bad resistors in the valve receiver section with to avoid inductance). Trying a few things, as checking the speaker wire connections for third time, bumped an RCA cable and full volume came back. Whew. Cheers, Adriel
I don't really have the budget for a Manley Chinook at the moment so please let us know when the new version of your phono preamp is available. You guys did such a great job selecting quiet and natural sounding tubes for my FreyaN. Good Advice on the electrolytics unless they are leaking or not working I wouldn't even think of replacing them until you mentioned it.
@@matthewhilty4209 Charles has started designing the new chassis and PCB's for the Modern Line Universal Phono Preamp (we still need a good name!) and hopefully we'll have them on order next week, then the fun begins! I normally build the first production Kit #1 and film it for The Build Series and then it goes out to Test Builders.
I am lovingly in stuck with a Herron Audio linestage which only takes six 6922's... the price of upkeep is steep... Though i cannot fathom any other direction of a component...
@@auggysimcity Well said! So I'm sure you've figured this out already, but in case you haven't, I'll share one piece of advice, in one word ... "spares".
Enjoyed your video and appreciate to learn of your business philosophy. One question in the realm of "tweaks" or upgrades to a system and which is more discernible: What is the sonic difference in your pre-amps, phono stages, or even amps between the PCB kits vs. direct wire, using exactly same caps, resistors, transformers, etc. . Using your comparative language used in your video, Is the difference, similar to sonic change between a $.20 cap vs. a $5 cap or subtle difference like between a $5 cap vs. $60 cap.
@@HoomanR17 we're often in a unique position to make a direct comparison, because the initial prototype is often point to point wired or a hybrid with some PCB's and some point to point. And there isn't any difference. Now that's partly because Charles is an excellent PCB designer and once a board is finished we both go over it for possible noise issues, shortest and quietest signal paths etc., then we do the review two more times before putting a board into production. On top of that we order the thickest board material available and the heaviest traces. So basically you have a well laid out point to point circuit rendered flat.
@@tubelab194 I have one question related to this as I've been looking at the insides of your amps. Does soldering to the PCB vs. using the screw down terminals make any difference?
@@HoomanR17 this is a very common question. And yes there is a difference, once you solder your wires to the PCB, you no longer can quickly remove the board for mods/repairs. What most people don't realize is that a high percentage of the wire connections made in electrical work are done mechanically without any (no) connectivity issues. What's important is to use a high quality connector (we do) and to carefully torque the connection so that you have solid electrical contact. We've used these junctions for all of our prototypes and production kits for years without a single problem. Caution! There are a lot of junk connectors/junctions, use only quality parts.
@@DG-rc6rr Power conditioners have nothing to do with power supplies other than they bridge the mains power at your wall and the power cord feeding the amp. IMO power conditioners should never be used, most likely they'll lower the quality of the power available to your amp. The exception being power plants which basically act as a clean generating station inside your home.
@@DG-rc6rr As far as I'm aware all SMPS are switching type. There are some very small power adapters that are transformer based, but they have such low current ratings you couldn't use them for an audio circuit or even to lamp a single tube.

Curious if you feel power conditioners and having a Linear Power Supply (vs switching) makes a significant difference for tube amps, in your opinion?

@@tubelab194 Thank you. And Linear Power Supply bricks, replacing an included power supply brick? Same thing?
