W7RY Ameritron Amplifier Replacement Capacitor Board 10 Capacitors

Description

W7RY brings you another amplifier innovation to help you improve your Ameritron AL-82, AL-1200 and AL-1500 linear amplifier power supply!
*************************
There have been several recent reports of diodes going bad. I have revised the parts list to a different supplier.
If you have ordered MCC branded diodes from Mouser, don't use them!
Please use Mouser P/N 863-1N5408G instead.
*************************
The board has space for ***** 10ea***** 30 mm diameter caps, a bridge diode arrangement with 20 1N5408 diodes, (to take place of the hokey daughter board arrangement in the stock Ameritron AL-82, AL-1200 and AL-1500) and a place for the small RFC, small protection caps, and diode that Ameritron puts on their boards.
Features:
- 10ea 30mm diameter 450 volt capacitors. Use 85c or 105c caps. Your choice.
- 3 Amp 1N5408 diodes
- 1/4” push on terminals can be used for all connections. Or just solder the wires to the board
- Terminal area is in the same location as the stock Ameritron cap board
- No more clumsy, hard to assemble daughter board for the HV diodes
- Either use one or two bleeder resistors per capacitor. Your choice of quantity and value
- Includes a location for optional HV OK resistors for non Ameritron applications such as the GM3SEK Triode Board.
- Has all parts as used on the stock Ameritron filter capacitor board
- High quality PCB with 2 ounce copper runs. (Standard is  1 ounce)
- lower cost 400K Ohm 1/2 watt (10 each) for the HV metering
-
Has an
optional
small 10 turn pot to adjust the HV meter so it’s accurate!
- About the same size as the stock Ameritron capacitor board and mounts on the same standoffs as the stock board. You must remove the two middle standoffs to accommodate the capacitors.
- Capacitors mount on the “bottom” of the circuit board with the bleeder/equalizer resistors on the top of the board for good air flow.
Parts for the board are around .00 for the board LESS CAPS. Choose your own caps. Either 105C or 85C caps that are 30 mm with 10 mm pin/lead spacing can be used.
All parts are available from Mouser or Digikey.
Parts list and instructions are sent via email
after
your purchase when you email me which is shown above. My "callbook" address works well too.
This auction is for a HIGH-QUALITY PC
board only
as shown.
All parts are available from Mouser. The parts list is included on the schematic which also has installation notes. This is not a kit. It is a bare circuit board only.
You must email me at the address shown in the pictures,
so I can send your documentation. Please include your eBay ID in your email.
Please don't email me through eBay! I cannot send it though the eBay email system because it does not allow attachments!
If you have
questions
, please email me
directly, not through eBay.
