Oade Brothers Audio now offering upgrades for your digital recorder.

Please e-mail Doug Oade to obtain an RMA number. Turn around time is approximately 10 to 12 business days plus shipping time.
Please note that older PMD 660s will not accept all upgrades as they use lower voltages for the audio circuits. PMD660s starting with serial number 2003 or 2004 will accept any upgrade.

The following Upgrades are available for any Digital Recorders in good working order.
Please note, our upgrade voids the factory warranty.
If we did not sell the machine with an upgrade installed, we warranty only the parts we put in, not the entire machine.
Please contact Doug Oade via E-mail to obtain an RMA number as well as shipping and payment instructions.

Introducing a new upgrade for the 661 !

Introducing the PLUS MOD for the Marantz PMD-661 & MKII. It can be added to any existing Oade Brothers MOD or installed into a stock machine along with the either FET, Super, Warm or Concert MODs. The stock machine with MIC ATTN set to 0dB and gain adjusted for 55dBV of gain to reach 0DBFS has a noise level of -50dbV. The Super MOD Plus, with the same settings, has -57dB of noise while the FET MOD Plus has a noise floor of -60dBV. This upgrade achieves enhanced performance by removing the internal mics and dual level mono. Please contact Doug Oade for details.
