UPDATE: 
NEW: M49 type bodies now in stock
GT-2B microphone bodies back in stock
Wood boxes for GT-2B, SYT-5, HT-11A and and U47 bodies back in stock


Now shipping high-quality, unmarked donor microphones for various DIY projects.  I am importing at quantity several models of microphones that have been identified as solid platforms for modification or complete circuit and internal component replacement.  These microphones and parts kits are sourced from well-established Chinese factories that have built a reputation for reliable quality.

I aim to keep these items perpetually in stock, so that folks will be able to purchase as needed when needed.  Given the bad economy, no need to "binge buy" extra projects prematurely  ;)  Hopefully, I've ordered a happy medium quantity so things will remain in stock for a little while on the first batch. . . enough time for me to pursue some other interesting items from the motherland.  But, if something runs out, a follow-up order will be placed in an attempt to maintain a reliable supply of these bodies for DIY projects and continued development of new microphone circuits.

Prices do not include shipping or sales tax for shipments within California.

C12 Circuit Clone kit designed to fit into the Alctron HT-11A or Apex 460 donor microphones.  This pcb kit designed by Matador is a faithful reproduction of the vintage AKG C12 microphone.  The power supply pcb is also designed to fit into the stock HT-11A PSU enclosure and utilize many of the stock components including the power transformer, IEC, switches, and jacks.

PCB's $30 ea.
Electronic parts kits  $80 ea.
Custom headbaskets $31 ea.

Alctron HT-11A (c12-type) tube microphone $160 - complete microphone kit - includes:

microphone
shock mount
power supply
7 pin xlr cable
plastic case

This microphone has been popularized by aggressive pricing from various name brand companies and is an excellent modification platform for C12-type builds. 

shipping weight 11.54 lbs.  - 11 lbs. 8.5 oz.
package dimensions 17x14x6 inches

Alctron GT-2B (short U47 type) tube microphone $170 - complete microphone kit includes:

microphone
shock mount
power supply
7 pin xlr cable
aluminum case

This microphone is also re-branded by several large brands and is an excellent modification platform with its stock circuit.  It is a short U47 type body and is an excellent donor body for ioaudio 's fine mk47 U47-based microphone kit as the PCB was designed specifically to fit a commercially available variant of this chassis.  I plan to stock 3 pin XLR inserts to fit this body as it may also be a good candidate for the FET 47 clone project by poctop. 

Note to people considering this microphone who are in Europe:  Thomann sells their house brand t.Bone SCT700 that is cut from the same tooling as Alctron GT-2B and is a cheaper option and body dimensions should be the same.  For US based people, shipping would tilt the price-point in my favor.  It is not confirmed, but I believe the finish on the GT-2B may be better than Thomann's option and the PSU provides more polar pattern options.

A limited number of these will be available without the psu's at $145 because mk47 and FET47 do not require the stock Chinese 9 pattern power supply.  I feel bad about wasting them so I will attempt to sell the psu's separately or negotiate to order some microphones in my next batch without psu and retain these in stock.

package weight 11.7 lbs.  - 11 lbs. 11 oz.
package weight - no psu 8.69 lbs. - 8 lbs. 11 oz.

package dimensions 17x13x6 inches

ShuaiYin SYT-5 (U67/87 type) microphone body kit $165 - body kit includes:

body
shock mount
3 switches (pad, treble roll-off, pattern)
high quality 35mm K67 capsule
capsule mount
7 pin xlr insert
3 pin xlr insert

$145 - kit without capsule (includes everything listed above without capsule)

This body is well suited for poctop's U67 clone pcb kit as well as his new U87 clone pcb kit.  The U67 pcb kit contains the necessary PCB to mount the 3 switches onto the microphone body, so this switch pcb is not included in the kit.  U87 and other projects will require a separate purchase of the switch pcb.  Poctop has supplied me with some stock of these boards and they can be purchased for $5.

Do you have dimensions for hte SYT-5 (or more direclty will it fit Gyraf's G7 boards?) If so, I'm in for one without capsule.

Will the Chinese 9 pattern P.S. (with or without Mods) work with  poctop's U67 Kits?
I'll take:
2 SYT-5 (U67/87) Mics. With or without P.S. depending on above answer.
2 GT-2B W/O P.S. (For U47 Fet.)

I do not know if the oem Chinese psu will work with poctop's U67 kits.  I suspect not as poctop's kit contains a PCB for the original PSU circuit that would probably have better filtering.  I would venture to say the U67 PSU PCB is too large to fit in the oem case also.  Dan from collective cases sells an excellent PSU case here on forum that is well suited for poctop's U67 kit.

The SYT-5 body kits are not complete microphones.  They do not have psu's or any internal components except the capsule and capsule mount.  I will put you on the list for

2 SYT-5 body kits
2 GT-2B microphones without PSU.

Please let me know if I have it wrong.

Hi,

Thanks for your interest.  I do not know if the STY-5 has the length required to house the Gyraf G7 board.  It certainly has the diameter, but until I can get a sample in hand next to a G7 board, I do not know.  I strongly suspect that it would be big enough, but cannot confirm.

hopefully someone can chime in here with better knowledge or, as these bodies become more widespread, information will be forthcoming.
