Apex 460 Mic Mod Service

Does your Apex 460 seem noisy, distorted, thin, bright, or harsh? We can fix it for you.

About the Mod

Our comprehensive upgrade for the Apex 460 (and all other branded versions of the Alctron T11A) replaces the mic's entire signal path: capsule, circuit, tube, and transformer. We also modify the power supply to correct its B+ voltage.

We install our Fox 460 circuit, including a selected low-noise 6072 tube and custom-wound transformer. The new circuit reduces the mic's noise and distortion dramatically, due both to our premium components and to design improvements in the circuit topology. The new circuit has higher sensitivity than the stock design, which improves the mic's signal to noise ratio.

We replace the mic's 32mm K67 capsule with our 34mm RK-12, an edge-terminated true large condenser design based on the AKG CK-12.

How it works

After you buy this service, see our Service Policies page for instructions on packing and shipping your mic. Be sure to print the Service Request form linked from that page.

Send us the microphone and power supply. It is not necessary, nor recommended, to send us the shockmount or cables or case. But it is critical to pack the mic and power supply carefully; both are heavy enough to damage themselves if the box is dropped.

The typical turnaround time is 5 business days. We can provide more detailed turnaround time estimates after you purchase the service.

Because this upgrade replaces the mic's entire signal path, it can be used on microphones whose capsule, tube, circuit, or audio transformer has failed. The upgrade does not replace the PSU, but we do offer various power supply replacement and upgrade options at additional cost, if your mic's PSU has failed or exhibits hum or noise problems.

Compatibility

We can upgrade the Apex 460 (all versions), the BadAax T11A, the Alctron T11-A, the Carvin CTM-100. We believe this upgrade is compatible with the Nady TCM-1150. 

This upgrade is not appropriate for tube mics with pad or filter switches,  such as the Avantone CV-12 -- although we have other mods available for those models. This upgrade is not compatible with the Nady TCM-1050.

Costs

The mod service includes the parts, installation, testing, and return shipping (domestic US only) from our shop back to you. 

Availability

This mod service is open to US residents only.

(Residents of other countries might find that it costs less to purchase a finished microphone.)

Optional Upgrades

We build custom tube mic cables with Gotham GAC7 wire and Neutrik connectors. This cable is superior to the thin, compromised stuff that claims to be Gotham brand sold on Amazon. We source the cable directly from Gotham in Switzerland.

If your budget allows for a superior power supply, see our VPS options.
