Yes, I'm using them and it would be that item: http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=KC006L-ND
Re: Current Limiting thermistor
Tom
For the F4 and F5 I used one CL60 in each primary winding and another from chassis ground to power supply ground, all per what was published in Nelson's service manuals. The Digikey number for what I used is KC006L-ND and they seem to work as expected with my toroids. No blown fuses and no hum or noises from ground loops.rickmcinnis said:Dear Peter or whoever has an opinion,
Are you using this in your amps?
Mr Pass suggests a CL60 thermistor to be placed in the primary of the power transformer.
I have know nothing about thermistors, other than what they do, so what is a CL60 thermistor?
Do you recommend these be used and if so would you recommend a part number, please.
Thanks,
Tom
MK132's for feedback
Dear Peter,
Thanks for the link for the thermistors.
Do you think there will be a heating problem with the substitution of 1.5 watt rated resistors versus Mr. Pass's specification of 6 watts?
How do the 75 ohms resistors affect gain?
I am in the process of collecting parts and always take an interest in what you are doing!
Thanks,
Rick McInnis

Sorry about that, answered my own question with something I didn't see before

Rigma,
For F4 on Peters PS boards,
I used four 33,000uf Panasonic TSUP
Digikey P6924-ND
For F5, I went overboard and ordered 4 P10014-ND 47,000uf each. Probably way overboard.

Diomedian said:It has previously been noted that the lead spacing of the resistors was 0.2", and that Peter recommended Vishay CFM-50 or Caddock MK132 resistors, both of which have 0.2" lead spacing. The Dales you use there are CFM-55s (or their military equivalent).

I have a stupid question to ask here.
I went around searching for cmf50 and noticed that most of the stock mouser has is only 1/4W or 0.25W whereas MK132 smallest is 0.75W.
appreciate advice what is the minimum requirement as the range is quite big from 0.25W to 0.75W.
Thanks again
