   Hi Bill, I found this Heathkit power supply, see below. 

 HEATHKIT HP-23C POWER SUPPLY AND SB-600 SPEAKER ENCLOSURE

 PRICE $105.00 + SHIPPING

 _The HP-23C Power Supply, Power Cable, And SB-600 Including New
Speaker Are NOT Parts Items_

	  [1] 

 THE HP-23C POWER SUPPLY AND SPEAKER ARE IN EXCELLENT WORKING
CONDITION AND BOTH HAVE BEEN SUCCESSFULLY TESTED. THE AXIAL LEAD
CAPACITORS BELOW THE CHASSIS HAVE BEEN REPLACED. THE 4 TALL BLACK
PLASTIC COVERED CAPACITORS ABOVE THE CHASSIS ARE THE ORIGINAL
_NICHICON _CAPACITORS AND THEY SHOW NO SIGNS OF AGING.

 THE 3 AMP RED PUSH BUTTON CIRCUIT BREAKER IS STILL INSTALLED AND
WORKS.

 THE 3 WIRE GROUNDED AC POWER CORD HAS BEEN REPAIRED BY A PREVIOUS
OWNER. THERE IS NO PROBLEM WITH THE REPAIRED SECTION OF THE AC POWER
CORD.

 THE ORIGINAL SB-600 SPEAKER HAS BEEN REPLACED WITH A NEW DB69 8 OHM
OVAL SPEAKER.

 THE HP-23C POWER SUPPLY’S BOTTOM COVER WITH 4 FEET IS INCLUDED BUT
NO TOP COVER.

 THE HP-23C POWER SUPPLY IS HEAVY SO IT WILL BE SHIPPED IN A SEPARATE
BOX THAN THE SB-600 SPEAKER ENCLOSURE.

 11 PIN POWER CABLE BETWEEN HW-100/101 AND THE SB-100 LINE OF
TRANSCEIVERS AND THE HP-23C POWER SUPPLY IS INCLUDED.

 THE HP-23C POWER SUPPLY IS WIRED FOR 120VAC PRIMARY POWER. SEE THE
HP-23C MANUAL FOR DETAILS ON REWIRING THE HP-23C POWER SUPPLY FOR
220VAC PRIMARY POWER.

 THE FOLLOWING “_NO LOAD_” OUTPUT AC AND DC VOLTAGES WERE MEASURED
AT THE POWER SUPPLY’S 11 PIN FEMALE SOCKET WITH 118VAC APPLIED TO
THE POWER TRANSFORMER’S PRIMARY WINDING, JUMPER USED BETWEEN PINS 9
AND 10 TO TURN POWER SUPPLY ON FOR VOLTAGE MEASUREMENTS.

 PIN 1 == MINUS 139VDC FIXED BIAS (NO VARIABLE BIAS)

 PIN 2 == FILAMENT COMMON

 PIN 3 == +374VDC LOW DC VOLTAGE

 PIN 4 == +856VDC HIGH DC VOLTAGE

 PIN 5 == N/C

 PIN 6 == 14.6VAC FILAMENT

 PIN 7 == DC GROUND

 PIN 8 == N/C

 PIN 9/10 == AC SWITCH AT THE RADIO THROUGH THE 11 PIN POWER CABLE

 PIN 11 == N/C

  Greetings to all , 
 I hope this message finds you well. 
 I have a good friend in SC, (Gary, AE1CT) who is trying to revive and
old Heathkit radio, and he is looking to buy a Heathkit HP-23 or PS-23
to power it.  
 Power supply specs..... Hi voltage....800v at 250ma 275v at 150ma
-100v at 100ma 12v at 5.5amps 
 I do not have one and all the ones he finds online are over $200,
which would be an ok price for a good PS, but when you add shipping
and SC state taxes, it becomes over $250 and he stated that was too
much for him to pay for an unknown condition PS. 
 If anyone has a Heathkit PS that Gary could purchase, please contact
me or him at the below listed e-mails. I am willing to pick it up and
ship it to him. 
 Thank you & 73
