Galaxy DX Radios EPT360014B and EPT360014C Notes:
In doing this I have
made a few notes you may find of interest. There will be updates to this section as I get along wth this project, so check back. |
PCB Grid Location B1 |
TR45 silk screen shows
the flat to the left on all silk screens used. All the board layouts on this site will show TR45 flat is to the right. |
PCB Grid Location C5 |
There is two places marked TR30 on the following silk screens KAI HWA2-002 V0, SM YGOI 94 V0. The Transistor in grid location C5 is TR39 TR30 is at Grid Location E4. The layout drawing on this site has TR39 labeled as TR39. Note that on the M-294 HB-C PCB silk screen TR39 is marked as TR39 |
Grid Location D6 & E6 |
C128 and C129 are swapped on the factory schematics (aka Tube schematics set) on some radios but not all. On all the layouts on this site C128 and C129 will be as the drawing to the left and this also this is also the way all versions of the silk screens used are. And the schematics on the site will be changed. Tube schematics errors
On the following schematics
the part labels are NOT swapped. |
Gride Location E6 |
On the KAI HWA2-002
V0, SM YGOI 94 V0 boards C130 silk screen label is closest
to the front. Also these parts are swaped on the factory schematics (aka Tube schematics set) on some radios but not all. On the following schematics
the part labels are swapped the part value's are right. On the following schematics
the part labels are NOT swapped.

Grid Location C2 |
The silk screen on all PCB's shows the flat of TR18 to the left. With a J310 installed in this location the flat is to the right as shown on all layouts on this site. |
The following applies to all PCB's (a)
There are two places marked R140. The layout drawing and parts list
shows these (d)
There are two places marked L50. The layout drawing and parts list
shows these as (e)
There are two places marked C84. The layout drawing and parts list
shows these as (f)
There are two places marked J102. The layout drawing and parts list
shows these as (g)
There are two places marked C84. The layout drawing and parts list
shows these as |
Factory schematics (Tube schematics set) there is an error on C101 and R115. The schematics show R115 to ground, but in fact C101 is on the ground side of R115 as shown in the diagran on the left.

DX33 - In
current production C170 is not in the radio and should not be on the schematic.
In early production C170 was installed on the solder side of the main pcb and
the value was 100pf.
DX44 - In
current production C170 is not in the radio and should not be on the schematic.
In early production C170 was installed on the solder side of the main pcb and
the value was 100pf.
DX55 - In
current production C170 is not in the radio and should not be on the schematic.
In early production C170 is not in the radio and should not be on the schematic.
DX66 - In
current production C170 is not in the radio and should not be on the schematic.
In early production C170 is not in the radio and should not be on the schematic.
DX73 - C170
was installed on the solder side of the main pcb and the value was 150pf.
This model is discontinued so all or most of them had C170 installed.
