What do you think about tube amp's consumption on our electricity bill............. Does it hurt that bad.

A friend says if you put 6 tube on your amp.................. It will consume your electricity like 2 aircon unit............

Are these true or what?

someone told me a Peavey Classic 30 consumes as much power as an average desktop PC. i wish i could confirm that.

Sa aking alam....
halimbawa may nakalagay sa backplate na rated 75watts
yun ang kain nya sa kuryente.... tapos output power nya ay 30watts
yun ang lakas ng tunog ng amp mo....
so meaning approximately times two....
So kung meron kang tube amp na Classic 30 (all tube)
meaning APPROXIMATELY mga 60-70watts
ang kain sa kuryente mo....  :D

correct me if i'm wrong

Iba yung POWER consumption sa POWER na nadi-dissipate ng speakers from the amplifier.  

BAMF or Bunyok, can you help out?

Actually yung sinabi ni rubis is already right-on. Power through the power plug is much higher than power out of the speaker terminal. This is because tubes use heaters, which are very power hungry, but whose consumption don't figger out in the speaker terminal. Like a single 12AX7 should be allocated 300mA of heater power, each. So for instance like the 50 Watter I'm assembling, if I did go all tube, I'd need a 2A transformer, just for the heaters. For 100W, ok na mga 5 Amperes. Heater pa lang yun, hindi pa kasama yung power na gagamitin to actually amplify the signal.

Actually sirs.........
It's a Guyatone GA-1500, 60W (72W on the plate), output section is 6L6GCx2 push pull and 12AX7 power section and transistor pre- hybrid amplifier.

Here is the front image:


Here is the back image showing the 6L6GC:


So is it true that this baby can consume as much as a 1 hp airconditioning unit?......................... :?:

I don't think so Sir Emil that your Flip amp  consumes
about 1hp like an Aircon...... i think it only consumes
around 150 to 200W tops.

1 horse power is equal to 746 watts.....  :D

correct me if i'm wrong. :D

skunkyfunk,
yun ang alam ko Sir ... mag kaiba ang power consumption
sa power output sa mga amps... dahil sa kain ng mga parts.
di katulad sa mga light bulbs....
OT a 100W incandescent bulb dissipates 100W
of lighting power...  whereas sa mga flourescent
lamps... 25W flourescent bulb can dissipate 100w
lighting power. kaya recommended ito...
napunta na ako sa bumbilya.... heheh  :lol:
hope this helps...

Naku many thanks sa lahat...............
Marami kasi akong kakilala na may studio....... Ayaw nila ng di-tubo na amplifiers....... Malakas daw sa kuryente kaya nag re-research ako regarding this............. So far medyo naliliwanagan na ko..........Tnx po. :wink:  :)

"malakas sa kuryente" is relative. Compared to what ? Of course compared to solid-states, they're monsters. Compared to your aircon tho', its not much.

Tapos pag naka-aircon ka, parang hindi lumalamig ang kwarto kapag meron kang malalaking tube amps. Tapos, ideally, naka-aircon ka pag nagpapatugtog ng tube amps (pero IMHO OA na masyado yun).

i haven't been into a rehearsal studio with tube amps though... but i heard that years ago, there was this expensive studio (you pay twice as much as the "other" studios) in katipunan where they have a half stack marshall and some tube combos... though frankly, i don't see the point with the half stack, but it would be cool to piss off your bandmates every once in a while by cranking it up :)

well.. if they have competent people managing it, i don't see the problem with having tube amps available in a rehearsal studio..

most rehearsal "studios" that i go to only have a PA. the point of this is, you're rehearsing your songs.. so use your own things..

it would be fun seeing a metal band using an acoustic amp! :lol:

yan ba yung power chord studio dati? 150 dun nung araw e...100 ang standard noon. may fender head + cab sila nung mga panahong yon, di ko alam kung anong model yon maski ngayon hehe. basta nabingi ako nung inoverdrive nung may-ari.

may standard 3-prong wiring ba ang mga venues dito sa atin? classified as death-defying stunt yata ang magsaksak/gumamit ng tube amp sa 2-prong/non-polarized outlet  :mrgreen:

Seriously, just plug it into an AVR and you get some form of isolation. Kung dati 220V nakukuha ng katawan mo, ngayon mga 50 volts na lang bwahehehe.

Gaganda pa ang tunog kasi mawawala yung ibang power supply hum and voltage spikes and dirty signals na nakukuha sa power lines.

sa pagkakaalam ko sir e thousands of volts ang dumadaloy sa high-voltage circuits ng tube amp. kahit naka-avr ka, pag tumawid na ang kuryente sa circuit ground, direcho yan sa guitar cable mo, gitara, at finally sa katawan mo. mabreak man ng AVR o house circuit breaker ang kuryente, nakatawid na. nadale na ang puso mo at nervous system.

kung pwede lang gayahin yung ginagawa sa electric stove e (i-ground sa gripo), kaso pangit yatang maggitara sa kusina :mrgreen:

yun ata yun... but i think they were charging 200/hr and im not sure about the fender head and cab... mejo madalang kasi head na fender e...

i'm pretty sure head yun bossing, na fender...kasi tweed ang balot tapos kita ang pag-ilaw ng tubes. then again, 1994 pa yon at madami-dami na rin akong nainom na alcohol since then :D
