3 years is a good track record and now it needs alittle care humm
That amp is exceptional i think,ive 2 egnater heads and redplated 3 tubes and blown fuses and fortunately only tubes and bias drift issues have occured .
Lucky me!
Yep reflector in russia make the new sencor tubes and saratov runs a GT line over there.
TAD Or Ruby may be sino tubes but sino tubes have a space at the top between 2 mica plates so you can tell.
Plainly you can see the 2 mica plates 3/16" apart and there sino or a very old tube 1960s .
I have...
Move the pickups down on the low E side some and try to EQ it cranked abit, it should be thick and full sounding but not bass dominate .
The mids will sound scooped with a big bass going on.
I should mention i want the p-90 for a schecter solo 6 custom Le , it sounded very thin and lifeless with the seymore duncan HB pups it came with.
The attitude p-90s give it is fantastic i think !
Im looking for a P-90 that has the best tone insted of overly nasty , but we all know all P-90 pups growl abit on those round low notes.
Ive found for sale a rio grande p-90 HB size,and missisippi queen p-90 then theres a few bare knuckle p-90 im looking at .
Rail hammer gnarly 90 too anyone...
For petes sake look at the jet city jca5012c with 6L6 tubes.
There web site has them on sale now for $399 and its a steal.
Effects loop is amazing with pedals.
I have the jca2212c 20 watt only difference is power tubes , mine are el84 .
These amps have some tone for sure,and a good natural...
I found the bias trim pot on the board and it was labled so i put my tube probe adapter and found only 5milliamp per each tube yuck.
I put the RI mullard el84s in and gave them 19 milliamp each.
Now she rocks,i went ahead and retubed all the 12ax7 tubes .
I found a post whom seems to know what...
Did you find out which preamp tube drives the high gain channel ect:
Id luv to hear what you discovered,i could not find any info.
Yes you did good changing preamp tubes , sino tubes breakup differently and there harsh ive found and there noisy.
The EQ recovery tube helps set the character of...
Im glad to hear the old school rock & roll is there,i have enough non sino tubes to help it be near its best.
When i was younger and less accomplished i liked high gain,now it would be to limited except for sporatic coniption fits.
What is the deference in the sound to your ears as we didnt hear it before the mod , you seem happy with it and it sounds very good thru-out the gain range but a little brighter lower on gain.
Im waiting on a jca2212c combo bought without trying it out,MF stupid deal was only $299.00 with...
MF stupid deal OTD JCA2212c $299.00 i reflected and quickly reviewed the amp on the tube.
Improved now with 2 channels,crunch and OD high gain.
Im looking for a natural breakup classic R&R and blues using P-90 humbucker sized pups on a schecter solo 6 custom LE.
Anybody tried one,im waiting...
1 ohm means nothing, check for continuity and get a beep on your meter will tell you it at least if voltage flows thru but not amps.
Check all fuses this way.
A bad tube seems possible , caused a short.
The OD channel is driven by both triodes in a 12ax7,try changing that tube i think it is v2 but check the tube layout at egnater.
You should be getting alot of gain,ive got more gain than needed but sino tubes distort horrible imop.
Tube roll that like i did,it effects the whole EQ on my amp.
The rebel 30 liked the TS and a Ruby ax7 select was too brite in there .
Ive read the Alchemist is a pre amp tube nightmare to get sounding good again .
Once you find which tube is the tone controls recovery tube you can begin to try...
I use these in brite amps like my laney vc-30 and i cant get my other standard Genalex back from my room mate after i tried it in his Blues Jr.
The highs are recessed so i dont no where else it would be good but v1 in brite amps.
This tube sounds very harmonic like rolling your heel back some on...
I tried numerous 12ax7 -12az7 tubes to find a unique but good tone.
I will give a quick synapsis.
GE ax7- good NOS tone but tooo brite for my rig and p90 with .022 capacitor.
Ruby ax4 ac7 good tone but too crispy and biting attack.
NOS RCA very good tone but pushed it became a darker than wanted...
