Collins 30L-1 Amp

 


January 18, 2024 - One last picture - Real ham equipment glows!




January 15, 2024 - More testing today. (Updated)

80M - 500W
40M - 500W
20M - 600W
15M - 500W
10M - 400W


January 14, 2024 - Checking the 30L-1 this morning on 80M and got 500W - very happy about that and consider this project a success.







January 12, 2024 - This past week I looked over the full 30L-1.  I verified all the capacitors and resistors looked good, fixed the meter glass putting it back in its proper place (was pushed in), forgot to change the meter lamp, and also added the MOV on the back for grid flashover protection.  Then I buttoned the unit back up and pending receipt of a few cables it's ready for testing with the KWM-2.





January 7, 2024 -  Put the 30L-1 amp on the bench to check it out.  Took the bottom cover off and the diode board looked good.  Also verified the small "fuse" and that the 2W resistor was changed to a 5W resistor.  Will check the back and add the MOV if necessary and check the capacitor board.  The meter will need to be removed and the glass ring fixed so the glass is in the right place.


December 9, 2023 - The amp arrived and it looks good - the tubes lit up and appear to be in good shape visually - I saw 2000v so that part is good - I didn't pull the case off but it appears to have the original diode and HV board.


December 4, 2023 - Purchased a Collins 30L-1 amp to go with my KWM-2.
