Hier finden sie die wichtigsten Informationen zum Matching unserer Röhren.
Wir bieten zwei unterschiedliche Matchings an. Diese unterscheiden sich wie folgt:
1. Unser Premium Matching:
Hierbei wird der Ruhestrom der Röhren punktgenau gematcht und auch die Steilheit (Transconductance) der Röhre gemessen.
2. Das sogenannte Standard Matching:
Die Röhren werden nur nach Ruhestrom selektiert, der maximale Unterschied darf max. 2,9mA betragen, eine Messung der Steilheit findet hier nicht statt.
Standard Matching, welche Optionen und Kriterien bietet das Standard Matching?
Das TAD Standard Matching beinhaltet ähnliche Qualitätsprüfungen wie beim TAD Premium Matching.
Die Röhren werden aber nur nach Ruhestrom selektiert, der maximale Unterschied darf max. 2,9mA betragen, eine Messung der Steilheit findet hier nicht statt.
Während der Ruhestromprüfung findet auch das Abhören auf Störgeräusche mit Klopftest statt.
Verhält sich die Röhre stabil und laufruhig, so wird entsprechend den Meßwerten, die TAD Grade Nummer ermittelt und direkt während der Prüfung etikettiert.
Diese Grade-Nummer kommt auch auf die Verpackung, so dass das Grading sowohl anhand der Röhrenschachtel als auch auf der Röhre selbst nachvollziehbar bleibt.
Matching- und Symmetrieoptionen für Vorstufenröhren
Paarweises Matching für Vorstufenröhren bedeutet, dass zwei geprüfte Röhren in einer realen Audioschaltung (Kathoden-Bias) die gleiche Verstärkung in jeder einzelnen Triode aufweisen, also vier charakteristisch identische Systeme.
Das Matching in Paare beinhaltet unsere Symmetrie- bzw. Balance-Selection (max. 10% Toleranz). Wir empfehlen das Paar-Matching für HiFi-Anlagen sowie bei allen Stereo-Anwendungen.
Premium Matching, welche Kriterien muss eine Röhre erfüllen um als Premium Selected bezeichnet zu werden?
Array ( [articleID] => 4209 [articleDetailsID] => 4741 [ordernumber] => RT431 [highlight] => [description] => 6V6GT-CZ TAD PREMIUM Matched [description_long] =>The TAD™ 6V6GT-CZ has been added to the TAD Premium line in 2020. It is a glass envelope beam pentode having a plate dissipation rating of 14 Watts with convection cooling. It is intended for audio frequency power amplification service in either pentode, ultra-linear or triode connection and single or push-pull/parallel applications.
The TAD™ 6V6GT-CZ has an extended plate voltage range which makes it ideal for higher power amplifiers like Jim Kelly and as an electric reliable substitute for overload conditions which are often seen with guitar amplifiers. Close manufacturing specification tolerances and improved processing provide enhanced reliability and superior sonic performance.
The TAD™ 6V6GT-CZ is designed to be a direct replacement for any 6V6, 6V6GTA, 6V6GTY, 6V6Y, 5871, 7184 or equivalent.Due to the higher voltage withstand the size is enlarged compared to other 6V6 tubes.Tested, selected and matched by TAD in Germany![esd] => [articleName] => 6V6GT-CZ TAD PREMIUM Matched [taxID] => 1 [tax] => 19 [instock] => 0 [isAvailable] => 1 [hasAvailableVariant] => 1 [weight] => 0 [shippingtime] => [pricegroupActive] => 1 [pricegroupID] => 1 [length] => 12 [height] => 5 [width] => 5 [laststock] => [additionaltext] => Single [datum] => 2020-01-10 [update] => 2024-04-24 [sales] => 114 [filtergroupID] => [priceStartingFrom] => 39,80 [pseudopricePercent] => [sVariantArticle] => [sConfigurator] => 1 [metaTitle] => [shippingfree] => [suppliernumber] => [notification] => 1 [ean] => 4251594910817 [keywords] => [sReleasedate] => 2022-05-26 [template] => [attributes] => Array ( [core] => Shopware\Bundle\StoreFrontBundle\Struct\Attribute Object ( [storage:protected] => Array ( [id] => 4754 [articleID] => 4209 [articledetailsID] => 4741 [attr1] => [attr2] => [attr3] => [attr4] => [attr5] => [attr6] => [attr7] => [attr8] => [attr9] => [attr10] => [attr11] => [attr12] => [attr13] => [attr14] => [attr15] => [attr16] => [attr17] => [attr18] => [attr19] => [attr20] => [satag_gefahrgut] => 0 [satag_rohs] => 0 [satag_alte_shop_id] => [satag_alte_artikel_nr] => [satag_volumengewicht] => 0.06 [satag_restposten] => 0 [satag_sperrgut] => 0 [satag_invalidate_cache] => 1 [nimbits_article_emotion_above] => [nimbits_article_emotion_below] => [nimbits_article_emotion_desc_above] => [nimbits_article_emotion_desc_below] => [nimbits_article_emotion_above_footer] => [faqid] => 5 [priority] => 5000 [replacement_article_ordernumber] => [arboro_manufacturer_country] => China [arboro_grundpreis] => ) ) [satag_properties] => Shopware\Bundle\StoreFrontBundle\Struct\Attribute Object ( [storage:protected] => Array ( [Tube Type] => Array ( [0] => Array ( [option_id] => 8 [optionName] => Tube Type [value_id] => 69 [optionValue] => 6V6/6P6P-J/CV509/CV-511 [value_path] => ) ) [Socket] => Array ( [0] => Array ( [option_id] => 9 [optionName] => Socket [value_id] => 1240 [optionValue] => 8 Pin(Octal) [value_path] => ) ) ) ) [marketing] => Shopware\Bundle\StoreFrontBundle\Struct\Product\MarketingAttribute Object ( [isNew:protected] => [isTopSeller:protected] => 1 [comingSoon:protected] => [storage:protected] => Array ( ) ) ) [allowBuyInListing] => [attr1] => [attr2] => [attr3] => [attr4] => [attr5] => [attr6] => [attr7] => [attr8] => [attr9] => [attr10] => [attr11] => [attr12] => [attr13] => [attr14] => [attr15] => [attr16] => [attr17] => [attr18] => [attr19] => [attr20] => [satag_gefahrgut] => 0 [satag_rohs] => 0 [satag_alte_shop_id] => [satag_alte_artikel_nr] => [satag_volumengewicht] => 0.06 [satag_restposten] => 0 [satag_sperrgut] => 0 [satag_invalidate_cache] => 1 [nimbits_article_emotion_above] => [nimbits_article_emotion_below] => [nimbits_article_emotion_desc_above] => [nimbits_article_emotion_desc_below] => [nimbits_article_emotion_above_footer] => [faqid] => 5 [priority] => 5000 [replacement_article_ordernumber] => [arboro_manufacturer_country] => China [arboro_grundpreis] => [supplierName] => Tube Amp Doctor GmbH [supplierImg] => https://www.tubeampdoctor.com/media/image/99/c6/62/TAD_Logo_RZ_2021_72dpi.png [supplierID] => 3 [supplierDescription] => Tube Amp Doctor GmbH [supplier_attributes] => Array ( [core] => Shopware\Bundle\StoreFrontBundle\Struct\Attribute Object ( [storage:protected] => Array ( [id] => 1 [supplierID] => 3 [nimbits_category_emotion_above] => [nimbits_category_emotion_below] => [nimbits_category_emotion_above_footer] => [nimbits_category_emotion_above_menu] => [six_seo_text] => ) ) ) [newArticle] => [sUpcoming] => [topseller] => 1 [valFrom] => 1 [valTo] => [from] => 1 [to] => [price] => 39,80 [pseudoprice] => 0 [referenceprice] => 0 [has_pseudoprice] => [price_numeric] => 39.8 [pseudoprice_numeric] => 0 [price_attributes] => Array ( ) [pricegroup] => EK [minpurchase] => 1 [maxpurchase] => 2000 [purchasesteps] => 1 [purchaseunit] => 0 [referenceunit] => 1 [packunit] => piece [unitID] => 9 [sUnit] => Array ( [unit] => Stck.
