New Tubes for Engl Screamer head
« on: January 11, 2011, 05:44:43 PM »
Current spec : 

I'd probably not want to play about with changing these or pretending I am technically minded regarding amps but it would be nice if I could get some new tubes in ( coming up to that time , like when you finally realise you need new trainers but could never be bothered buying any).

Is anyone capable of fitting and testing these once advised if I take the plunge.

Preamp:
4 channels, Clean, Crunch, Soft Lead, Heavy Lead, single 3 band EQ,
Lead Presence, Reverb, Bright switch, 3 x ECC 83 preamp tubes.

Master section:
V.L.S. (two different master volumes), 50 watts
(1 x ECC 83, 2 x 5881 power amp tubes)

i re-tubed mine recently with a jj full re tube kit.(they have a normal & high gain option for the pre's).
check the eurotube web site under engl models.i also bought a multimeter, bias sockets and fitted them myself.
i read and re read how to lots of times first.i also assumed the grid plate voltage as per the eurotube site based on the average they've experienced with this amp. meaning i then only needed one  reading of 37-42ma in the tube socket/biasrite.the trim pot for adjusting this reading is on the pcb inside the amp, it's a tiny white plastic screwhead
but easy to locate.it was as far clockwise as possible with the stock tubes (ie from new) and i needed to turn it
completely anticlockwise to get my 37ma reading.
it was easy to do, the first time i'd re-biased an amp, took about 1 hour and i was DEAD careful.
it sounds great, a little warmer than before.
my last 5 or 6 posts in the players section are with the new tubes.
hope this helps
by the way there's loads of places to buy your tubes , i'd heard good things from eurotubes and they also had the multimeter
and bias sockets cheap as well as info for this amp(i think it was 100pounds for everything)
have a tech do it with your tubes if you don't feel confident enough.

Is this likely to improve the sound though?  Eurotube example.
 Engl Fireball, Screamer, Thunder & Classic, High Gain Option.   [1]   $95.50
 --ECC83S-HG-K   [3]   
 --ECC83S-HG-B   [1]   
 --6L6GC Matched Pair.   [1]   
    Total:   $95.5

It is more me and my GAS. I felt it was time to buy something again :).    I'd prefer something a bit different sound wise rather than fitting a whole load of same or similar tubes just to go well its certainly better but a few days later becoming bored by the sound again :).  ( fussy I know).   

Could well go with the above anyway.  Anyone from the UK ordered from them?

i ordered mine from france, i'm english(wife french) and used a uk credit card , without probs, took about a week if i remember right and i didn't get charged vat or import charges(just luck)
i went with the normal option but have read of poeple being happy with the high gain option, check out the 'unofficial engl forum', that's where i started.

I'd go for TAD. Worked great for my Engl Classic.

V1 7025 highgrade, rest 12AX7A. Simple but effective.

Power tubes depends on what sort of character you want. There's a load of 6L6 and 5881 tubes you can choose from.

In my Classic I have the 6L6WGC-STR.

For a 'jack of all trades' like the Screamer I'd probably go for the 6L6GC-STR or the 5881WXT-R.

I've had 2 tube changes in my screamer, stock --> EHX --> JJ. EHX sounded warmest with most harmonic content but slightly less gain than stock.

What is required for the Engl screamer 50 head specifically the preamps.  Does one order all premium tested 12AX7 / ecc83 Tungsol 9 pin preamp valves  for V1 V2 V3 V4 or do you need a V1/Phase spitter.

I am a newbie so confused by the phase inverter and in particular what I need to order exactly to replace my engl screamer. Don't worry I've asked hotrox but on the off chance someone knows about this particular amp.

Useful links however I am not ordering from there and the guy from that website basically started patronising me by informing me what I already know " it is not a high gain amp" and basically said replace the tubes with what is already in it which isn't the sort of road I want to go down. I'd save myself cash and continue as is if that was the case.

I am not talking about tube failure here in my existing head!.

Anyway hopefully hotrox will get their arse into gear Monday as they have clearly gone into coma state as its the weekend n all.

have you tried picking up the telephone and asking them? - if you want an immediate answer, thats your best bet.

also, what are you wanting to change in the amp's tone that it doesn't do now? - if you like the way it sounds now, why f*uck with it?

do you want a tighter bass response? 
more bass?
less treble?
smoother overall tone?
more headroom?
less headroom?
fatter mids?

post some info and I'm sure you'll get some good suggestions from forum members here.
