Collins 30l-1 manual

Am I missing something with my reasoning but I am thinking that I should be making my replacement choke with 26 or 28 gage wire?

The over all length of the inductor would be much shorter and probably fit within the RF cage easier. K9STH , Jan 2, It looks a lot like the Z that I just installed. Glen, does my thoughts about the gage of the wire to wind a new inductor sound reasonable to you? The 11 amperes is for chassis wiring, not power transmission.

Also, the 11 amperes is for air cooled at degrees C. For degrees C the current carrying capacity has to be reduced to a factor of 0.

The temperature of the plate choke is probably going to be greater than degrees C plus the wire is not going to really be air cooled. Therefore, I would use at least 20 gauge wire. Hi Glen, Thank you sir. I was under the impression that DC current through this inductor was the primary design consideration for three reasons.

So, I assumed that the RF current through this inductor would be very low. Lastly, the physical size of this this inductor is so small. If the original one was wound with 20 gage wire would it not have been a lot longer? I appreciate all of your help. It features dual meters. The lockable front cover reveals a clean interior. The rear panel has an SO type antenna jack. Fully tested with new delay tube and dial lamps.

Only putting out watts from possibly weak tube. Designed with indented carry handles on the side. Too big to ship. The used items on this page have been sold!

Mine, I get an easy watts out from the 's and don't! Go to the B's! Art Collins designed this for what it was. Use it!!! Glenn, VE6ND. K9RJ Rating: Quality! The Collins is rock solid and if you ever need to repair or re-tube it is easy. I think it looks as good as the day it was made.

Far superior to Heathkits and modern 'cheap' amps. Thank you Art Collins for a wonderful amp! The Collins 30L-1 was one of only a few HF amps which could add value to my hybrid station: a Kenwood TSs, an all band doublet fed with real ladder line and a Dentron MTa tuner.

That's why I searched for one. It is the rare QSO that doesn't include a comment on my great signal and beautiful audio quality. I live for those comments and wouldnt trade one of them for all the S-units in the world. This is why I got back into the hobby after 45 years. Time Owned: N. Quiet as any amp with tubes ever made!

One thing that doesn't get discussed enough is the audio quality this amp delivers. Obviously if the exciter is junk, the audio will just be amplified, but with all things in the exciter being good, the cleanliness of this amps audio is simply amazing and pure. Yes, today you can buy amps which run the same tube compliment, but starting with the paper like cases they are wrapped in and the lightweight components the Collins is in quite another class,period!

For the price why would you even consider another? It's that good and I own Alphas, Henry's etc. Art Collins really knew what he was doing when he designed this. So many electonic experts will put it down abt this and that being wrong. Got a new board that is very nice, installed that and got new B tubes..

I run mined on V and like to see the lights in the aprartment flash. It puts out watts on all bands key down. Dont run it on RTTY. In a cw or ssb contest I lift the lid and put two fans on top of the RF deck to suck out the heat. Always wanted one of these just to say I have one.

Have had many many amps over the yrs and this is just a fun, easy to tune amp with the Collins name on it.
