The best Side of mechanical mod
Also, the tone controls in the first amps ended up a “cathode follower” variety of arrangement, with the second phase of V1 getting used being an impedance converter, which adds no gain.
In the intervening time I've swapped in the upper worth resistors, to guard my electrical power tubes a bit, and haven’t noticed any alter to my tone. My power tubes now see a voltage of all over 330V.
The reality that it’s not designed for the Tailor made Basic just implies that it won’t be a drop-in substitution, so there'll be some drilling involved. Normally you’ll really need to drill 3 holes as You should utilize one of the pre-present holes.
Brass also comes in several grades. The costlier alloys have an increased level of copper, which translates into more robust efficiency. Naval brass is tough 60 p.c copper, admiralty brass is all over 70 per cent copper, and aluminum bronze is about 90 per cent copper.
[…] has prepared an article on a variety of modifications executed to improve its tone and playability. This Vox AC15CC mod posting aims to generally be a hassle-free reference resource for all those desirous to conduct their particular mods on […]
FWIW – if any of you can get tempted to select up an AC15CC1 on Unique due to new AC15C1 product, like I did, A few of these mods allow it to be a much more usable amp. Pre-mods, and also put up vivid cap removal, I had been even now getting a Laser Beam of Deathtreble® out with the dome of your speaker that has a mic (or positioning myself ideal before the amp the place i could listen to what the mic was). Which was employing humbuggers, neck PU, treble rolled waaaay back.
Probably attempt some JJ EL-eighty four’s and find out if that can help improve your reduced end. JJ’s are proposed as an improvement over the inventory valves the amp comes along with.
Plated pins also need special care. Brass and copper pins could be treated Along with the solutions pointed out earlier mentioned. Gold-plated pins can ordinarily be washed which has a gentle detergent to get rid of buildup. Besides delivering the most beneficial conductivity, silver-plated pins may also be quick to maintain.
Thanks for the valueble recommendations! I’ve received a lot better thought! If your purpose is to decrease the resistor value from 220K to 180K, what about to leave the current resistor “as is” also to increase One more variable resistor in parallel? At this time less do the job associated and you may in no way go better than manufacturing unit parameter. I've An additional dilemma for yourself, nevertheless… I play by way of a speaker cab with 16Ohm Blue Celestion in it. Amazing speaker, BTW! So, I have found that when amp established on 8 Ohm output the cab Appears improved, brighter, louder, tighter, regardless of what, Evaluate to “of course right” change location on 16Ohm.
Keep in mind that enter jack board? You ought to be in a position to cling it off the other facet of your chassis now, out of how. I use some sticky tape at Just about every finish and in the middle, to hold the board when I Focus on it. This should now give you sufficient usage of the solder side of your board to de-solder parts Latest e-juices from Vape Cave etcetera.
I was pondering When the Tone Cut Mod by replacing the reverb quantity pot could also incorporate reverbs foot-switching capacity so that you could switch involving a hard and fast resistor and An additional price based on wherever the pot is set? Does that seem sensible which is it feasible?
I noticed 1 comment Having said that you had an image that confirmed the treble relationship connectd to ground however , you said that was Improper. Any solutions?
All that his mod requires is linking the unused lug of your bass pot to ground. The easiest way to do this, is to make use of the bottom lug from the volume pot of the highest Increase channel.
