H&K!!
Its German and it is made like old germans equipment.All amps are build like tank.And it is high quality electronic parts.(except Blue edition which are build in far east.)
Beleive me, I am expert for H&K amps.
I have next H&K amps at home:
-Blue Edition 30DFX
-Blue Edition 60R
-Tour Reverb head
-Vortex 212 combo
-MATRIX 112 combo
-ATTAX 100 head (old)
-ATTAX 200 head
-ZENAMP combo
-Edition Tube 20th Ann
-Tube 50 combo
-Tube 50 head
-TRIAMP Mk1 combo (6L6GC power tubes)
-TRIAMP Mk1 combo (EL34 power tubes)
-Puretone combo
-CC412/25
-AC112
-SC412
-QUANTUM 310
-Warp Factor (2 stuck)
-Tubemann II
And I still looking for Duotone, ATS120,CS100 or CS200 :screwy:
I like them all.They are diferent, even 30DFX and 60R.10 inch Jensen speaker is more direct, with punch and more middle tones (Blues).60R have 12 inch Celestion with more smoth and warm tones(Fender clean and drive with more bottom).
Quality of build Randall amps is not the same.They sound nice, but if you need amp, for verry long time, buy H&K.
Possible smal problems:
-if you buy old amps (10 years or more) you can have problem with crackling potenciometer.Do not use contack spray,they help only for short time.Use contact oil.They help for long time or change potenciometer.But they are hi-quality in H&K.
-If you buy Blue edition series and one day are switched on, but not working-any sound, try to check LINE IN-LINE OUT.This connectors are bad quality and you can eazy put from LINE IN to LINE OUT one guitar cable.If they are start working, make short cable for this or change this connector for more quality.
-If one MATRIX,WARP,Tour reverb or VORTEX do not have enough power or loosing power, you shoul give to repair.It is usually problems all (transistor) solid state amps:
-power resistor (broken, burn off, leg broken or need to be solder again).This is verry usually for Marshall valvestate.
-If you have tube amps can be only tubes.
BUT REMEBER!! NEVER SWITCH ON
ANY TUBE AMP WITHOUT CONNECTED SPEAKER.OUTPUT TRANSFORMER WILL BLOW-UP.THIS IS 100%.
You do not have this problems with solid state amp or combos.Good luck.And try amp before you buy.Like I said: even BLUE EDITION sound very diferent with diferent size speaker.
Even old H&K amps are much better then mostly all new amp.I recommended TRIAMP Mk1 for all, but if it is 600-800 EUR too much, buy TUBE 50/100 (280-380).Forget all new CRATE V33,V50,Peavey Valveking.......I have all this amps too.They sound good but they need to be repaired verry soon.
Good Luck again.Sorry but I better read then write German.
And only part of my amps on photos:
