Request a quoteQuestions about this part
Where can I buy the Joslyn Clark TB113-1?
This part is in stock at Z Power Electric and ships from our Calimesa, California warehouse. Z Power Electric is an independent MRO supplier in Calimesa, California — we buy outside authorized distribution, which is why we can quote parts that a standard distributor shows as unavailable.
Is the Joslyn Clark TB113-1 discontinued or obsolete?
Manufacturer lifecycle status changes by part number and region, so we confirm it per quote rather than publishing a claim that may be out of date. Either way it does not change what we do: we source discontinued, obsolete, and backordered parts as a matter of course, and the quote states whether we located the original or are proposing an equivalent.
How long does it take to get a quote on the Joslyn Clark TB113-1?
We respond to every sourcing request within 24 hours, and the quote states a confirmed ship date rather than an estimate. Mark the request urgent if the part is holding up a line.
Is Z Power Electric an authorized Joslyn Clark distributor?
No — and that is the point. Z Power Electric is an independent supplier, so we are not limited to Joslyn Clark's authorized channel or its order book. We source through surplus, new-old-stock, and independent inventory, and we state the condition and source channel of every unit on the quote.
