Pultec PSU cap question

[jeroddumas]

I just got my pultec boards and they look fabulous. Can I use 330uf/400v caps in place of the 220uf/350v. I have some of these laying around.

Yes, higher voltage and higher capacitance is better, but not the opposite.

What boards are these? Are these for the EQP-1A?

 

[jeroddumas]

yes the are the gyraf peq-1a.

I've noticed the bleeder thread. what size bleeder resistor should I use on these caps? Would a couple of 220r 3watt resistors work?

 

[gyraf]

NO!

Rule number one: Always check with Ohms law..!

220R at 250V will be 1.1 Ampere, 284 Watt.

if you need, use some 47K/2W or 100K/1W resistors.

Thanks Jakob. Will it hurt If i leave these bleeders in place permenantly? Just solder them across the leads of each ca and then leave them there. No loss in performance to the eq right?

 

[gyraf]

Not much loss anyway. Maybe a bit more ripple voltage, as the HT is not stabilized.

It will do with a bleeder on the first capacitor - the second one will discharge through this.

Thanks jakob.
