It’s not you Tony, it’s the amps. Higher wattage tube amps have significantly more headroom than lower wattage tube amps.
She wants your attenuator to blow up or your amps to blow up?!You 2 know I’m busting balls for using attenuators.
I know my girl wishes the fuck mine would blow up already!!!
I'm curious too and have never used the 88's so I'm quite sure one day, in the not so distant future, you'll see that I have joined the "Club". The BBTE(Biggest Bottled Toob Evar)club stuck in a mini Marshall. Couple a real throbbers if you will.
On your first point @PelliX, I’ve read where some manufacturers are now, or maybe have been, going back to the original, (different than a el34), 6CA7 design.
Did not know bout the 120’.😮At the same volume, perhaps. If you deduct those dB for the 20 watter - then not per se.
I don't mean to ruin your day (and I'm very much still digging my KT88's in the SC), but you know the KT120 is out, right....
Note that depending on the age the 6CA7 is a beam tetrode or a pentode like an EL34. They started out different, but manufacturers started simpifying their product ranges while retaining the name.
Also, to the best of my knowledge, the SC20 *always* shipped with JJ exclusively in all position. Marshall stopped using Shuguang valves in the DSL line beore the SC20 was launched. The problem wasn't reliability or poor sound, but consistency. Shuguang generally sounded nice, but were a bit of a gamble. There's a sticky on the forum for the Marshall Valve Codes which provides a bit of insight into "what's what".
My amps!!!She wants your attenuator to blow up or your amps to blow up?!
Hopefully she means the attenuator,…
I’ve gone back to using my attenuator, I found a sweet spot that virtually retains all the dynamics of the amp.
It’s only a few db’s being attenuated, but I able to crank the amp up around 8 on the master and 6 or 7 with the preamp, in the 20 watt setting.
A nice blend of power amp and preamp saturation, I wouldn’t be able to do that without an attenuator. I downloaded a db meter on my phone, just to see what the db range is in the room, it was around 88 to 96 db’s.
But I don’t know how accurate these db meter apps actually are.
Yes, those pics of the your SC20 tubes are all the same tubes that came in mine.Well, EHX (New Sensor) do seem to have them:
If you compare them with their EL34, you can see that they're quite different - maybe I should snag me a pair soon...
Sovtek/GT/EHX/etc (New Sensor)? JJ don't use the classical design:
Not sure about Shuguang and co from China.
The preamp valves should have a VLVE-xxxxx code which, with any luck, is in the sticky for the valve codes. I can also confirm mine were all JJ. Leme dig up a pic.
That's not quite the same; switching the output mode on the SC is actually dropping voltage on the output stage. The voltages all round are a bit lower on the SC than their bigger brothers in 'high' or normal mode, plus they're cathode biased which gives them more sustain and makes them a little more spongy if you wish. If you compare headroom on a 2204 and a 2203, however, the simple 'wattage' of the amp will not change the headroom.
That’s sig line material. 🤣‘When @solarburn Talks, Scozz Listens.
Yah I do like the EH 6CA7's . Hopefully they'll do good for you too. I've used them in my a DSL50/40, Origin, SC, Plexi, 900 anywhere where 34's were the power tubes. They are a fav of mine. Always a win when the expense is less and tone is good.@solarburn I've decided to take @scozz 's advice and give your approach a try. Before the Russian stock dries up, I've ordered a few EH 6CA7's. So far I think the JJ KT88's are the best sounding in the SC, but I'll gladly be proven wrong (and for a lower price!).
Why all the noise issues with pedals?So I was having a lot of noise issues with certain pedals and it was starting to get frustrating. I couldn't even use my GE-7 because it's so noisy and my favorite OD (MXR Classic OD) is pretty noisy, too. I couldn't hardly play my P-90 guitar because there was so much noise. Well today I found a Rocktron Micro Hush pedal in a box when I was looking for something else. What a great pedal! I've got no more noise and it doesn't seem to do anything negative to the tone. I can even play my P-90 now with my pedals on and it's quiet as can be. I don't remember ever buying this pedal, but I'm sure glad I did.
I don't know. It's not every pedal, my Bad Monkey, SD-1 and BYOC Reverb are dead quiet, but my 2 MXR classic ODs and my MXR Custom Audio Electronics Boost/OD and my GE-7 and MXR 10 band are really noisy as soon as I turn them on. I thought maybe they didn't like my 1 Spot power cord so I tried batteries in them and they're still noisy. It's not my cords or patch cables either, I checked those, too.
Yeah, I read @Dogs of Doom comments too, and I’d love to give 88’s a try. But man, these tubes are expensive for me, a bit too rich for my blood, (do people still use that old saying),
