I'm seriously considering having TAL build me a 2a3 amp but first I need some advice. What would be the best transformer to get from the options listed to begin with. Thanks in advance.

Hi,

I purchased a 2A3 from TAL this past summer. I realllllly like the amp. Best audio decision I have made. You can reach me off line if you want to talk about some possible upgrades for your TAL amp.

Regarding transformers, here is what I did and would do:

1. Output transformers: Hashimoto. I really like these

2. Power transformers: I do not like the Hammond that came with the amp. I am going to get a different, hopefully upgraded brand like Lundahl, Electroprint or Magnequest, Dave Slagle or Monolith.

IF you have the money, get want you want the first time around. Don't think about upgrading latter, assuming you have the $s.

Contact me for info: banpuku@mac.com

andy evans Audiophile Posts: 4378 Joined: October 20, 2000	I'm pretty happy with the Lundahl iron I have. I think a higher primary sounds better - the LL1663 is 5K into 8 ohms. LL1664 is 3K.

banpuku Audiophile Posts: 1008 Joined: January 19, 2006	Andy, do you prefer the 5K over a 2.5K? My Hashimotos have 2.5K or 3.5K and I am using 8ohm speaker output. Currently using 2.5K. What is the supposed benefit of 3.5k? Pat
