CLICK HERE FOR MAIN Hi-Fi PAGE
 


Akai / Roberts Reel to Reel tape recorders / decks utilized a 'sleeve' / adaptor to slip over the capstan to increase it's playback and recording speed. Tapes were recorded at many different speeds. All the way from a very slow 15/16 ips thru 'blazing' 30ips. The slower 15/16ips and 1 7/8" speeds were typically used for 'speech' / 'spoken word' recordings where recording quality was not as important and bandwidth demands were not there as with 'music' program recordings.
Many 'pre-recorded' tapes were recorded at 3 3/4ips and 7 1/2ips for higher quality.
For the best recording quality, many recordists choose the faster writing speeds of 15ips or even 30ips. This was generally reserved for recordings where the absolute best quality sonics and sound were desired. These speeds were commonly used for recording bands in the studio.
Of course the faster the tape moves, the shorter the recording time available.

AKAI / ROBERTS-Rheem
7.5ips 'LONG' SPEED SLEEVE
REEL TO REEL TAPE DECK
CAPSTAN BUSHING / SPEED CHANGE SLEEVE / ADAPTER
MADE OF "HARD ALLOY, NON-MAGNETIC 7075 ALUMINUM" IN THE USA!
for sale

This is a new capstan bushing / speed change sleeve / adapter for certain Akai & Roberts-Rheem Reel to Reel Tape decks such as the;

Akai M-8 / M8, X150D, X-150D, 1700, 1710, 1710-W, 1710W, 1710W/L, 1720, 1720W, & X-5000-W models and Robert's model 720A, 997,1630, 1680, 1725 8L III and maybe others .

This allows the faster, better quality, 7.5 ips playback / recording speeds to be achieved. Without this you will only be able to do the slower speeds of 1 7/8ips and 3 3/4 ips
(while some of these decks were originally designed to play 15ips as well, this required a '15 ips kit' which had an 'optional', additional and different speed sleeve and a smaller pinch roller. At this time we are not manufacturing either the 15ips sleeve nor is there a source for the smaller 15ips pinch roller).

If yours is misplaced then here's the fix.

These are new speed sleeves machined to exact specs and made of "HARD ALLOY NON-MAGNETIC 7075 ALUMINUM", not soft brass, that has a short life, so the locking dovetail will not wear. These fit snug and will stay on with a perfect fitting "locking notch" joint machined to perfection. Each one is individually tested with factory test tones at 400Hz and 1kHz, and monitored on an HP, dual trace O'scope for any wow and flutter issues!

-- These fit and are machined to perfection and do not have the WOW and Flutter issues that many of the one's that are being sold
on-line auctions exhibit. We often hear complaints about those and end up selling ours to replace them. --

These enable you to play / use the faster 7.5 ips tape speed if your deck requires a capstan sleeve to do that. We are always investigating which Akai Reel decks these will fit. We do know it will fit the above listed decks. If you do not see yours listed PLEASE DO NOT EMAIL or CALL to ask if it will, as we do not know yet. This is a "work-in-progress".  As soon as we discover additional models that this sleeve will or will not fit, we will post that info. STUDY THE PHOTOS CLOSELY TO DETERMINE THE FIT FOR YOUR DECK. 
We know these do not fit X-4000D, 4000DB, 4000DS, 4400 or some of the "M-" series as they use a different sleeve.


"Just to say the new Akai capstan speed sleeve completely sorted out the problems with my machine - sounds  sweet! Thanks." -  Miles, UK

"Hello Jerry, Just wanted to let you know the Akai speed sleeve I ordered arrived today. I appreciate the fast service and the helpful comments you made during the ordering process.

 FOR DECKS WITH AN OUTER
'RIDGE' / 'LIP'

MADE OF "HARD ALLOY, NON-MAGNETIC 7075 ALUMINUM" IN THE USA!
for sale

This is a new capstan bushing / speed change sleeve adapter for certain Akai & Roberts-Rheem Reel to Reel Tape decks, whose rubber pinch roller has a small ridge or lip on the outside edge (the 'edge' or 'lip' was originally designed into these pinch rollers to keep the speed sleeve and I suppose the tape 'in place' but was really un-necessary, as the speed sleeve generally stays in place by it's own pressure), such as the;

Akai M-9, 1800 series, X-1800SD, 1800-DSS X-2000S, X-2000SD models and Robert's model 770X SS, 771X SS and maybe others .

This allows the faster, better quality, 7.5 ips playback / recording speeds to be achieved. Without this you will only be able to do the slower speeds of 1 7/8ips and 3 3/4 ips

NEW ADDITION
AKAI / ROBERTS-Rheem
15ips / 30ips 'SHORT'
SPEED SLEEVE
REEL TO REEL TAPE DECK
CAPSTAN BUSHING / SPEED CHANGE SLEEVE / ADAPTER
MADE OF "HARD ALLOY, NON-MAGNETIC 7075 ALUMINUM" IN THE USA!
for sale

This is a new 15ips**  / 30ips* capstan bushing / speed change sleeve / adapter for certain Akai & Roberts-Rheem Reel to Reel Tape decks.

**HOWEVER, NOTE; YOU WILL NEED THE ORIGINALLY SUPPLIED, SMALLER DIAMETER RUBBER PINCH ROLLER TO ALLOW CLEARANCE WHEN MACHINE IS IN 'STOP' MODE. WE DO NOT HAVE THE RUBBER PINCH ROLLERS AVAILABLE, ONLY THE METAL 15IPS SLEEVE.

These will fit and MAY** allow 15 ips** speed on such Akai reel to reel tape decks as the;
Akai M-9, 1800 series, X-1800SD, 1800-DSS models and Robert's model 770X SS, 771X SS and maybe others .
Should also function on the Akai M-8 / M8, X150D, X-150D, 1700, 1710, 1710-W, 1710W, 1710W/L, 1720, 1720W, X-2000S, X-2000SD & X-5000-W models and Robert's model 720A, 997,1630, 1680, 1725 8L III and maybe others.

**This allows the fastest speed of 15 ips playback / recording
(*or potentially 30ips playback / recording speeds on the Akai GX-365D*) speeds to be achieved so if you have tapes recorded at 15ips, you can now play them back correctly. Also, if you are making new recordings and want the best quality sound possible, then increase the 'writing' / recording speed to 15 inches per second. This sleeve will allow that.

CAPSTAN BUSHING / SPEED CHANGE SLEEVE / ADAPTER
MADE OF HARD ALLOY, NON-MAGNETIC 7075 ALUMINUM" IN THE USA!

This is a new speed change sleeve / adapter for certain versions of Akai & Roberts Reel to Reel Tape decks such as the;

This allows the faster 7.5 ips
(15ips on the GX-365D) playback / recording speeds to be achieved. Without this you will only be able to do the slower speeds and won't be able to achieve the higher quality recording / writing speeds of 7.5ips.

If yours is misplaced then here's the fix.

These are new speed sleeves PAINSTAKINGLY machined to exact specs* and made of "HARD ALLOY NON-MAGNETIC 7075 ALUMINUM", not soft brass, that has a shorter life.
*(We actually modify them slightly from the originals, so they 'lock' better on the capstan, reducing capstan 'spin' and potential for 'slowing speed')

Included Hex nut and Washer now made of 'Non-Magnetic', 'Stainless Steel' (not currently in photos above).

-- These fit and are machined to perfection and do not have the WOW and Flutter issues that many of the one's that are being sold at on-line auctions exhibit. I often hear complaints about those purchased elsewhere, and end up selling mine to replace them.

**While the original style of 'top nuts' are not currently practical to source or manufacture, we are now including a 'hex nut' and lock washer that, while lacking in the cosmetics of the original, does function fine. You typically do not need any tools to tighten or loosen as fingers usually do the trick.

B) The part that you have found is NOT marked as SOLD or SOLD OUT.


If you do not see it listed after thoroughly searching the pertinent page

nor do we maintain "waiting lists" for parts,

Sorry, but phone and email traffic for parts
we don't have listed or for parts that are already marked "SOLD" has become too consuming of time resources.

If you don't see the part you are looking for, simply check the web page periodically as we never know what will show up each day. Thanks!!!!!
