BC-375E and BC-342

 

June 25, 2025 - First power up with just the VT-25 (speech amp)  tube in it.  I have the other VT-4 tubes on order.  The BC-375E can operate in CW mode with just the Master Oscillator and the PA tube in place.



June 25, 2025 - Ordered the four 211 tubes yesterday from a Chinese supplier on eBay - just under $135 per pair.  Also some old pictures of BC-375's in action.  Bid on a dynamotor today.





June 23, 2025 - Got the painting completed.  The paint on the tube cover is still a little wet, so I expect it to look like the right upper antenna tuner panel when dry.





June 22, 2025 - Today on the BC-375 I masked off and painted the antenna tuning unit top half and a small section on the left half of the main control section above the band tuning unit and a small section of the lower antenna tuning unit.  I also painted the sides.  I still need to paint the cover over the tubes, the top of the unit and the back.



June 21, 2025 - Checked the tubes in the BC-342 and found one of the 6C5 tubes tested bad so I ordered a replacement.  Here's the inside of it.


 

June 18, 2025 - Here's the BC-342 - it looks great - will be testing it soon.



June 15. 2025 - Here's what the tube complement will look like and their functions.  In my unit someone replaced the second from the left tube with a 5-pin socket and a HY-69 tube.  I have purchased a 4-pin socket to put it back as a VT-4 tube.



June 14, 2025 - Picked up the equipment.  I got seven tuning units for the BC-375.

 TU-5B        1500-3000kc            (two)
 TU-8B         6200-7700kc            (one)
        TU-10B        10000-12500kc       (three)    
TU-26B        200-500kc            (one)

Here are some pictures of the inside.





June 10, 2025 - Will be picking this all up on Saturday.


June 4, 2025 - Just bought all this for $250 - The BC-375 is a little rough but complete per the seller.
