Seller's Description





This is a New Old Stock 1B2 radio pentode valve (equivalent to DAF91) designed to run on a low voltage battery "Accumulator" supply with a 1.4V Heater and with a low HT voltage usually between 45V and 90VDC. Originally released in 1940, the 1B2 was one of the new generation of miniature B7G base valves that made small portable radios a much more realistic possibility. Ideal for a beginner to the world of valve radio construction and used in many of the classic simple two valve regenerative radio circuits. Manufactured in the 1960's and 70's. Current stock has the "J" suffix indicating manufacture/test to military specification.



B7G 7 pin base.Limited quantity of these hard to find vintage valves available, so don't miss out!


See our store for other listings for 2P2, 6N5PJ, 6SN7, 12AX7, 12AT7, 12AU7, 12AX7B and for "old school" construction genuine 7025 preamplifier valves as well as matched pairs of 6V6, 6L6 and EL34.

<Handy hint> Changing your valve


Once you have the back or cover removed from the amplifier/radio/record player you are changing a valve in it's easy to change. First, the safety warnings;

Unplug the unit from the mains before removing any covers.

Don't try to change the valve when the unit has been recently switched on... valves get hot enough to burn you!

Try not to touch anything inside the unit except the valve you are changing as some parts can hold high voltages even when it has been switched off for some time.

Now for the easy bit.... hold the valve you are changing between two fingers and your thumb and rocking it slightly to free its pins, pull it firmly straight up and it will unplug. You will see that the pins form a circle with an inner plastic/Bakelite peg with a bump on one side.

Take a look at the socket to see where the indentation on the centre hole is and taking the new valve, line the centre peg up correctly with the gap and again rocking it around slightly (only a few degrees) push the new valve in until it is firmly seated. Replace back cover, switch on.... all done!

Preamp valves like this double triode don't need any further setting up or baising, so thats all there is to it. Changing these valves can make your sound instantly brighter and punchy, so why not spend a few pounds and bring the life back into your amplifier!



Should you be in any way unhappy with your purchase within 28 days of purchase, you may return the item for a full refund of the purchase price.

If you are ordering from more than one of our listings, note that we can offer you reduced combined shipping ONLY if you use "Buy it now" on all items then request a total from seller BEFORE making payment. We will then send you a combined shipping invoice to pay. This is NOT possible if you have already paid for any of the items you are ordering.

Customers in Italy please note that due to the high number of orders that vanish and never arrive whilst in the hands of the Italian postal system, we will only send orders under £22 in value to Italy via standard untracked airmail. If your items total more than £22, please arrange to pay for tracked and signed shipping so that your order may be shipped safely and securely. If this option is not offered in the listing, please use the following listing to pay the extra cost of this.
 

Also note that orders sent to Italy may take MUCH longer than eBays estimate to be delivered and, whilst some orders do arrive within a week or two, many orders sent to Italy are not delivered for three or perhaps even four weeks! This is entirely outside our control, as we ship within two working days and once your order is in the hands of Poste Italiane, there is nothing we can do to get it to you any faster. 

Please DO NOT send messages with the title "Item not received" as these open complaint cases against us and damage our seller rating! Instead please use the general "Other" heading to ask about your delivery if several weeks have passed.

Lastly, all please note that when asks you "Did the item arrive on or before" their estimated delivery date, it also damages our seller rating if you answer "No", so bear in mind that we always ship within two working days, so if you answer "No" because your local postal service (especially in Italy!) has taken weeks to deliver, you are punishing us, not them!

Thank you all for your kind consideration of the above and remember that we will always do our very best to sort out any problems or questions you may have related to your order if you contact us using the "Contact Seller" and (if the choice is given) "Other" ask a question of seller options.
