Z1 kit new build by Radarek
09/18/19 at 17:22:30
 

Hello

I'm new to the tube world so to start with I have decided to build a kit first to understand the process and then maybe go with one of Steve's creation... plus been not building anything for last 20 + years makes it even more fun

Board is on the  way. Now I'm working on the shopping list hence have some questions:

Transformers: will it make any better if I go with Hammond for example. PT and OT or just OT? Steve specifies that We can use any OT with  primary impedance between 3000 to 9800 ohm, what will be the difference based on primary imp? Can I use multiple outputs: 4or8or16. Would prefer to use   8 or 16 as this will suite my speaker best- altec 604e.

Resistors: would it make any sense to upgrade them to Audio note or takeman for example?

Capacitors:  which one to upgrade? Signal path to Jupiter HT for example?

Internal wiring: any specific wire to be used? Tinned copper 20ga would be good?

Sorry for bagging with those questions, all input highly appreciated.

Regards
Darius aka Radarek

P.s. English is my second language so excuse me all the spelling and gramma    mistakes...

Thanks

The Board arrived Friday. Shipment from Mauser is on the way and should be here Monday end of day. Went with stock parts as for now. Still a few are missing but should be here end of week. I have spent all weekend on reading all the threads in Zkit1 forum as far back as 2009. That gave me a bit of understanding of typical problems this amp had, and how it developed over the years. Great stuff.

Going to order trannies now... really thinking about Hammond iron.... 1608 for output and 372fx for power? Any suggestions? At least that what a search is giving me...

Case - probably will go with one of the hammonds stuff...

Still thinking about better coupling caps...

Is a silver wire good for jumpers.

Regards Darius

Update...

All elements been soldered in. Proper tube sockets arrived today... jumpers made from 99.9% silver 1mm solid wire. WBT silver 4% solder. All components soldered from both side( reflowed). Took around 1 hour to do all, now need to clean a bit of residue from the board after soldering. Big wait for the transformers begin....

Regards
