Paul Hynes Z100A regulator with CCS1A constant current source + K&K Time delay

[OliverC]

Hello everbody,

Unfortunately, I am not able anymore to purse some of my planed DIY projects and must part with components that I specifically acquired:

Here a set consisting of:

• Paul Hynes Z100A regulator configured for 100-200V (it works also with single-ended valve designs!), I aimed at building with it a state-of-the-art tube preamplifier
• The regulator can be enhanced with Paul Hynes constant current source CCS1A (mine is configured for 20mA but this can be reconfigured by changing a resistor)
• Finally, a fully assembled K&K time delay module for delayed B+

I would require 185 USD including PayPal and shipping.

Many thanks for looking!
