Upgrade for Day Sequerra FM Reference Tuner


I have a Day Sequerra FM Reference Tuner about 1992 vintage that works perfectly. I understand there are upgrade mods that are available.
Does anyone know who does these or if they are still available and whom to contact?

I stumbled across this thread and I can offer an update:

Since HD radio was added, many tuners suffer from added noise in Stereo.  The upgrade that Day-Sequerra offers now includes an added filter.

Ironically, Day-Sequerra is a big commercial supplier of HD broadcast gear.

21 year old thread.

hifigeezer you must be bored. Most of the posters likely gave up on FM at least a decade ago!

That Sequerra upgrade for $3800 will  buy a Marantz 10B, and it will sound more convincing. I'm one of those FM weirdos- 67 Mac MR 71. Arguably, 2nd place to 10B.

If one REALLY  wants to play with a serious  tuna, the REL Precedent is my pick. It's what Saul Marantz based his creation on.

The upper  level Scotts are contenders.
