GB for F6 Convertible Clone boards

[necplusultra]

F6 with primrose transfos

just thought I'd show how the primrose transformers look like with the teabags's f6 boards. These are fully potted.

regards.

Very nice! I am jealous of your PSU caps. DIdnt think much about PSU caps until I changed brothers RIAA stage from NIchicon Kg to Siemen Sikorels. I fearfully say I could hear the difference.

necplusultra,

Nice indeed! What's the rating for those and any idea on how much do they weigh? Thanks for posting.

Do the rectifier diods rellay need cooling?

Very cool. Can you let us know what are the values for the M-Lytic's and possible source?

I don't see Mundorf listing 35V rated electrolytics on their main site.

MLyctic caps: are rated 15 000 uF at 35V. They were sourced from parts cnxn about 2 years ago. unfortunately, they are no longer available. I always try to use them for my high-end builds. They were originally for an F5 but I ended up using 33000 uF to fit the pd psu boards. I like better Teabags psu boards. Alot better quality I find.

Rectifier,: using ixys bridges for the F5 and I am sinking them since they do get hot. Not sure for the mur's although I tried them on the F5 and they did get hot . Sinks may be an overkill.

primrose: rated at 2 x 18v @ 300 vac. they weigh 2.8 Kg according to sumR spec sheet. I get 19.4 V off-load but they should attain 18v with the amps connected. rated at 8.35 A per 18v winding.

note: there's a GB for the primrose currently brought to us by buzzford ( no pun inteneded , thankz buzzford!)

hope this answers everything.

unfortunately, they are no longer available.

Yeah, thought so... the new ones are a bit larger and rated at 40V.

But why two PSU boards? And two transformers? Going fully dual mono?

Also, when you get the chance... can you please let us know the physical dimensions of the transformers? Trying to see if I can cram a fully dual mono in the chassis I have.

Actually, the group-buy is brought to you by buzzforb (not sure what the pun was, but anyway...)

Update.
I am about to close GB. I made error in figuring cost, only pricing in one pair of Jfes. I also did not get correct number for power resistors. The price of the kit will go up $7 to $68. I will give everyone a couple of days to back out, if you want.

 

[dimkasta]

you forgot to update the total calculation. I did that for u

 

[buzzforb]

THank You.

 

[Ryssen]

So are the 2sk170/2sj74 going to be inlcuded in the kit?

 

[buzzforb]

Yes. I mistakenly figured for only one set instead of two. If i did not pass it on, I would take a decent loss on the kit.

 

[necplusultra]

is there a price for kit without fets

 

[buzzforb]

IF you don't want the Jfets, then just subtract $20 and add note to the form. I do not mark the J-Fets up. They come from Spencer.

Hi:


There´s any PCBs kits left?

Optional Dual Rail Power supply is available as well?

I am interested if any.

Thanks

 

[buzzforb]

Contact TeaBag through PM about the boards. I sell the parts for the boards.

 

[acccruz]

I will do!

Thank you for your help.

I have removed myself from the parts GB;too many projects.
