Gundry Filter Circuit Now Available
We can install this circuit on just about any preamp. Originally designed for Carver Sonic Holography, this filter can be incorporated into many kinds of audio signal processing or media sources. The filter can be turned on or off by a jumper, or with a switch wired into it.
Sonic Holography Frequency Response (stock):
Sonic Holography Frequency Response With Gundry:
Note the two 'dips'. This enhanced equalization expands the holographic imaging of the SH processing to our natural, non-linear perception of sound location.
The circuit requires +/-12 supplies and space to mount.
Dimensons: 60mm X 70mm (2 3/8" x 2 3/4")
It's function is to attenuate 2 frequency bands which our ears are naturally very sensitive too, such as baby crying and sirens. By adjusting the frequency response of some audio processing, such as Sonic Holography, the result is a better sound image, especially at high volume levels where certain mid-range frequencies dominate our ear/brain system and smear our perception of depth and detail in the music.
Special Offer!
Price: $40 (PCB with parts) or $50 installed (in addition to standard service fee).
Contact us at Service@nelionaudio.com to purchase yours today! We assemble these by hand here in the USA!

Testimonials
"Greg,
I just wanted to thank you again for the outstanding restoring of my PLs [Phase Linear 200 and Phase Linear 2000]. I am in awe of the clarity, punch, and full sound range coupled with my B&Ws. I do not remember the PLs sounding this good back in 1980!Thanks Again,"-Tim B"About 1 1/2 months ago, my beloved Carvers (1.0t amp, C-1 preamp) stopped producing output. They have never been serviced since I bought them in the mid 80s. A bit of research found Nelion. From the first email contact I felt very taken care of. Friendly, straightforward, even accomodating. In 2025!
Setup, shipping and payment were as smooth as could be. The advice was spot on. The units came back a couple of days ago, on schedule and at the price quoted. I’ve spent three days in music heaven. What an amazing job you guys have done! They sound so damn good. Thanks to you and your entire team."
-Bob H."Dear Greg and Jenny,
I received my Carver M1.0 mkII op2 amplifier back and hooked it up. It sounds fantastic and looks great with the blue led’s. It is such a warm sounding amplifier. Very quiet. Like Picasso painting on black canvas when I listen to my tidal Master recordings. Better imaging, more transparent, warmer, cleaner, I could go on and on but you already know all of this. I’m so impressed and want to personally thank you for your incredible talent." - Sheldon H.
"Hi Greg,
The amp arrived earlier today. Put into a system with a Sony TAE 86 preamp and ADS 1230 speakers.
I had been using the matching Sony TAN 86 Class A amp. I’m the original owner since 1980 and had them completely redone last year. And I thought they sounded great.
The difference is huge. I am blown away. The music brings tears to my eyes. To say the upgrade [M1.0t mkII opt002] is worth it would be a gigantic understatement.
Thank you." - David W.
"Greg,
INCREDIBLE SOUND!" - Kenneth K.
"Hi Greg,
The amp was delivered this morning, and I’ve got it hooked up. It sounds GREAT!!!
Thank you so much! I will make sure to share this positive experience with all my solider buddies who probably need theirs refurbished too.
I have goose bumps. 😄 " - Gerry S.
"Super!!!! Thanks!!!!! The amp’s sound is exquisite!!!!" - Fredrick L.
"Hi Greg,
Holy Smokes! These sound absolutely incredible! I was honestly wondering if there would be an audible difference. Unreal. Very happy! Any productivity I hoped to accomplish today went down the drain.
Thank you very much for the quick turnaround!" - Chris W."Hello Greg.
I just received my M1.0t back from your shop and I wanted to say that the amp sounds wonderful!I can't thank you enough for your outstanding service, backing up your reputation with solid service and expertise that took a problem situation for me and turned it back into a wonderful listening experience!
Thank you for the warranty work and your willingness to go above and beyond to make this customer satisfied! My 1989 Carver never sounds better!
I wish you all the best and highly recommend anyone needed to bring their Carver amps back up to original speed, to GO TO YOU before anyone else!
All the Carver Best!" - Dan J
"Hi Greg
I have been out of town and just hooked the 4000t up yesterday. I had no idea how much a preamplifier could improve the sound of my little Hafler SE120 amp. You did an amazing job. I am very satisfied.
Thank you!" - Jon S
"14 day after receiving, M1.0MK II Upgrade
= Mind Blown!!!
What an incredible difference!
Thank you for restoring true audio and completing a 15 year dream." - Blake F
