Hi,
as you know Wolfey has done fantastic job on modding his GDs.
He is using 0.125W 38k resistor.
I can buy this resistor locally http://www.maplin.co.uk/p/metal-film-06w-39k-ohm-resistor-m39k
This one is 0.6W 39k and I'm not sure if difference in W makes any difference . 0.125W and 0.6W.
Can I use 0.6W instead of 0.125W ?
Thank you very much for your help

Thanks for your kind words.
As I stated in my PM's back to you, .6W 39K should be fine.
The main purpose of the wattage spec of 1/8W resistor is that the physical size is not too big to fit and the wires on the resistor are not too big to fit over and solder to the solder points on the pcb.
De-solder the 36K and replace it with the 38/39K resistor. You can solder it across the two solder points put there for the resistor / capacitor network. They left the capacitor out during manufacturing so there are two extra points one can use to solder the resistor wire across them.
Simply solder the new resistor in place like I did in the attached pics.
Here are the pics of my handy work. Please excuse the left over resin (black stuff) around the resistor connections. I didn't have any pcb cleaner on hand at the time, but the resin won't hurt a thing as it is completely non-conductive. Just looks a little bit messy

Red wire (+) intentionally connected to the tiny fuse (FB25) as it's easier to solder to than any other point.
Fan start-up current is 140mA for 1.2sec then levels out to 78mA constant.
Tin your wire (if it isn't already) before you solder to the fuse terminal so as to keep from accidentally de-soldering the chip from the pcb. This way, it only takes a second to solder the wire to the terminal.
If this helps you, please feel free to show your appreciation by sending some coin.
Not mandatory but, very appreciated!

Make these modifications at your own risk!
Peace!

Pea Ess, if you want me to make these modifications for you, PM me and we'll discuss it.
I am certainly qualified to do it, without bricking your pod of course!
Thanks for the photos. How safely can we mix and match these mods? Right now I don't have an iron tip fine enough to do the soldering mods. I either need to modify something or order something. I am interested in the pencil mod and the fan mod tonight though. Would this be safe?
