How about spend a little more time on building amps like the DSL which I like very much and i'm glad the power tubes are chassis mounted! im already seeing disappointed customers on the new build. Spend more time wiring the chassis mounted tubes like the 800 series ect. People respect the quality going into them and less problems and breakdowns! Edit: I see they designed it in a different way looks promising
Now I'm perplexed. I just traded my 40C, for the 40CR. Did a side by side, and everything. The CR sounds a lot better. A lot more versatile, and usable range. Torn now. Do I take it back, get my old one, throw the V30 back in?
All due respect, but if you want the same quality in a DSL that goes into a JCM800, you're going to be spending much more for a DSL. A DSL is intended to be a low cost amp, there are going to be trade offs.
Biased it last night, at 36. The new one was already biased at 35, though I evened it out a bit. Even with the V30, the old DSL does not sound as good, as the new one. I just finished playing the new one, with a brand new "V-type" speaker, and was playing it dime'd. You could never do that with the old one. At least I couldn't stand it. Playing it with everything set at noon, doesn't sound bad, either. Treble is a useful EQ setting now. It's a lot fuller sounding. The OD2 channel, sounds pretty darn close to a JVM now. I haven't put my Marshall V30 in it, yet... And I may not, just because the China V-Type sounds really good. And its brand new. Has maybe 30 minutes on it.
set it to 32, 36 is still a bit hot sounding on the red I had a few people loving it a lot better now
My tech recommended 30 to 32, 450 to 500 plate voltage. I dig the red channel with creamback. Thats the problem everyone thinks its supposed to be hot there wrong on these its preamp distortion hotter wont sound any better that's what Dean told me. I tried a few 30 32 36 and back to 32. More heat more problems he said!
Who gives a shit where the tubes are mounted? Lots of amps are made this way. ALL TUBE AMPS GET HOT. I’m sure modern amp designers took this into consideration. If the amp sounds better, keep it.
While this could well be, 32 on a PV of 450 is under 60% dissipation. As long as it sounds good, it can run hotter and not hurt anything. Tube amps run hot.
It really does sound like a winner..I don't want to return, and most likely won't. Too late, unless I'm gong to bias the new one at 32. Which is, really, really easy with the new setup. No other mods. Just a well broken in Marshall V30. It's probably not a problem, and there's a lot of amp makers that do it nowadays, though typically they should be mounted on a separate board. I am not against PCB. I'm against poorly manufactured PCB. I've already taken a bunch of pics, and played it a while. Was going to do a short clip with some playing, and post a NAD thread. However, I'm going to the store to get my daughter's birthday card (it's tomorrow)... then I'm going to pull the chassis out, and take lots of pictures. I will share them all with you guys tonight. Here's some teasers...
Those red/black connectors are the bias trim? That's pretty damn easy. Only thing better would be to put the ports on the back panel.
I like those bias points. Easy enough for the serious user or tech to bias. But not so easy that a curious person can adjust them. Was a major annoyance to balance an amp (at least 50 watters) with a few books then bias it. This also keeps the DIYers away from the high voltage, so that's a good thing. I wouldn't worry about how the power tubes are mounted or wired. It's a nice feature for amps to use flying leads, but this requires a person to do the work and PCBs will reduce the costs.
That I couldn't tell you. Never owned a Creamback. I like the sound of the original V30. Now compared to that, I haven't put my Marshall V30 in the new amp yet, but I do know I really like this "V-Type," and it certainly sounds like a V30. I suspect, it's the Chinese version of the V30, with the UK specs. Though, I could be wrong.
In a really cheap amp. My Egnater is PCB mounted tube sockets, and its nowhere near the build quality of the Marshall. Never had a problem with it, running 6V6, or EL34. The guy that posted that on Facebook, is being a bit reactionary. Kind of like I was, before I gave it a moments thought.
Actually, the original 2000 series amps had board mounted tubes, that combined with the traces caused them to cook themselves. So, the H series of amps won in that respect, with the HR I guess the new upgrades meant downgrades elsewhere. That said, if you want chassis mounted tubes, chokes, big caps, flying leads, put your money where your mouth is and buy a 2203x.
It’s a combo. All the heat goes straight up into the board anyway. You think maybe they’ve thought of that since the very few issues that the 2000 series had in 1998! When I started working on cars 20 years ago, the engines computer was located in the car, behind the dash to prevent heat/stress damage. 2018...they’re located right between the corrosion proned acid battery and the exhaust manifold under the hood!!! They never fail..
