"Dragonfly" my version of the Atari 7800 SD cartridge

["Dragonfly" my version of the Atari 7800 SD cartridge]

I got mine in the mail about 2 weeks ago and finally got some time to play with it.  I have one of the 1st gen 7800 NTSC consoles (with the expansion port--manufactured in 1984).  It has the Composite A/V Mod from vintagegamingandmore.com.  When I use the Dragonfly cart, TIA sound can barely be heard.  However, POKEY and YM2151 are near perfect.  When I plug in a 7800 Cart, TIA sound is spot-on.  The Dragonfly's firmware is up to date, BTW.

 

Is there something wrong with my console or Dragonfly?  What am I missing?  What could I look at?  Thanks in advance!

I updated the list .

 

ATTENTION!

Unfortunately, starting today I am quarantining due to a positive test for Covid, so I will resume further shipments in about two weeks.  

Take care of yourself. Prayers for a speedy recovery.

I’d like to order one in purple with PokeyMax and Yamaha.
