Default PS Schematics

At the risk of sounding like a broken record, I too could use schematics to the PS 4.5 AND the PS 5.0. The 4.5 is working fine, but never hurts to have info on hand. The 5.0 I began working on 2 years ago but had to shelve the project due to life. My notes have since disappeared (two kids and 2 cats) and I don't remember where I was with it, so a schematic would be more than appreciated.

For those who do own one of these preamps, I can tell you that the switches and wafers are still available through Allied Electronics. If anyone needs part numbers, I'm sure I can dig those up.

Thank you in advance to anyone who wishes to send me a schematic. My email is jebsledge@gmail.com. Thank you again!!

Count me as another broken record.
I have a PS IV + HCPS I bought new '82. It's given reliable service all these years until yesterday when I noticed a "burnt circuit" smell near the unit. It works & sounds fine but the LED never stops flashing.
Should be an easy fix if I had the schematic.
Please?

It's not hard to find schematics on forums that cater to older gear (and that have file hosting space) but for some reason I can't locate a complete schematic of this simple preamp. The original owners manual had a schematic of the phono stage but nothing else and I've found versions that include the line stage and power supply. None include the power-on timer/safety circuit or whatever it is.

Hi Greg,

I PM'ed you last night for the schematic as well. Thank you!

Anyone here has any other information, the timing/protection circuit, etc, for the PS preamp, please send it my way(soda_audio@yahoo.com). There will never be too much information on these good old gears.

Thanks in advance!
Stanley
