| KT120 on Copland CTA-405 integrated amp Each tap has two wires, not one.....I still think you have 7a total for the filaments. Just call or email your builder for the specific answer to this question to be 100% sure. | |
| KT120 on Copland CTA-405 integrated amp Your transformer is made up of several sections or windings. The 6.2v winding for the power tube filaments is what is suspect for the KT120 tubes. The windings for the B+ supply are fine.Will the situation with the filament draw over-taxing your t... | |
| KT120 on Copland CTA-405 integrated amp Looking into it.......in general. Based on what you told me, your pushing it. Again as Wolf said, it may work fine, but I would check for overheating as you don't want the unintended consequence of a tranny failure in a year or two... | |
| KT120 on Copland CTA-405 integrated amp Yates, good idea. Amps will work, but the tranny may be taxed and lead to premature failure down the road. It may take a couple of years but.... | |
| KT120 on Copland CTA-405 integrated amp Ya, your amp is a PCB board. Can't tell from the pictures. | |
| KT120 on Copland CTA-405 integrated amp If you have only one 6.2 tap coming out of your tranny - meaning you only have that one winding for your power tube filaments, then follow the wires to the power tube it goes two. It should hook into pins 2 and 7 of one of the power tubes. Usually... | |
| KT120 on Copland CTA-405 integrated amp Yater, I assumed 7A max spec on your tranny. I may be mistaken as your tranny may well have TWO 6.2volt/7A taps meaning you have a total of 7A per side (two tubes). If this is the way your amp is wired, then you are all set.Just make sure you have... | |
| KT120 on Copland CTA-405 integrated amp The filament tranny I purchased has two taps and each one rated for 6A. This works great as the max needed is 4A per two kt120's. | |
| KT120 on Copland CTA-405 integrated amp One last comment. It may "work" fine and you may think all is well....however, over time you may bring your output tranny to a quicker then usual end. The fact that your output trannys can handle 100 watts has nothing to do with your power tranny ... | |
| KT120 on Copland CTA-405 integrated amp As I understand it each power tube will require the rated filament juice. In this case KT120's will pull from the 6.2v 7 amp taps. Each KT120 requires a minimum of 1.7A. Four tubes x 1.7a = 6.8A. The tranny is rated for 7A so.....However, the KT12... | |
| Capacitor log Mundorf Silver in Oil Thus far I have put Duelund CAST caps in my preamp, and three tube amps. Each time the improvement was absolutely revelatory. The music always maintained great tone, texture and body. I must have meat on the bones and the CAST do this in spades wh... | |
| Review: Tube Research TRL Dude Tube preamp Abruce, are you up to coming to Southern MN? I am 10 minutes from the Iowa border and the Dude would love to meet a new line stage. | |
| Review: Tube Research TRL Dude Tube preamp I am in Southern Minnesota and come by! Perhaps we can work out a time? | |
| Amp repair...What to expect. If Bill worked on your amp rest assured it will sing better than new with 50 hours or,so of burn in. | |
| Most Musical amp? Tube - Musical Reference RM9 - I have owned many a tube amp and this 20 year old is the most musical I have owned. I upgraded the coupling caps to Duelund CAST and this amp sings! |
